Henrik Rydberg 57157becdd Input: bcm5974 - adjust major/minor to scale
By visual inspection, the reported touch_major and touch_minor axes
are a factor of two too small. Presumably the device actually reports
the semi-major and semi-minor axes. Corrected with this patch.

Rusty Russell 9bbb9e5a33 param: use ops in struct kernel_param, rather than get and set fns directly
This is more kernel-ish, saves some space, and also allows us to
expand the ops without breaking all the callers who are happy for the
new members to be NULL.

The few places which defined their own param types are changed to the
new scheme (more which crept in recently fixed in following patches).

Since we're touching them anyway, we change get() and set() to take a
const struct kernel_param (which they really are).  This causes some
harmless warnings until we fix them (in following patches).

To reduce churn, module_param_call creates the ops struct so the callers
don't have to change (and casts the functions to reduce warnings).
The modern version which takes an ops struct is called module_param_cb.

Éric Piel 7f29f17b57 Input: elantech - discard the first 2 positions on some firmwares
According to the Dell/Ubuntu driver, what was previously observed as
"jumpy cursor" corresponds to the hardware sending incorrect data for
the first two reports of a one touch finger. So let's use the same
workaround as in the other driver. Also, detect another firmware
version with the same behaviour, as in the other driver.

Reporting this will allow GUI config apps to correctly scale
width sensitive config values (such as palm detect) to correct
range.  Current user apps are detecting kernels min/max=0/0 and
making an assumption that it means 0/16 or 0/15.

but driver forces to 0 when no fingers on touchpad.

Chris Bagwell 2a8e77102e Input: synaptics - only report width on hardware that supports it
Synaptics devices report fixed value of 5 for finger/palm widths
on devices that do not support capability and driver further
hardcodes to 5.  Stop reporting this fixed value when its not
supported since its not useful.

This will aid applications so they can better auto-enable support
for multi-touch emulation and palm detection logic using finger
width only for devices that support width detection.

I can find no applications that currently require existence on
ABS_TOOL_WIDTH. Since only synaptics and bcm input devices
currently support this tool, it seems they must handle it
gracefully.

Wolfram Sang fbae3fb154 i2c: Remove all i2c_set_clientdata(client, NULL) in drivers
I2C drivers can use the clientdata-pointer to point to private data. As I2C
devices are not really unregistered, but merely detached from their driver, it
used to be the drivers obligation to clear this pointer during remove() or a
failed probe(). As a couple of drivers forgot to do this, it was agreed that it
was cleaner if the i2c-core does this clearance when appropriate, as there is
no guarantee for the lifetime of the clientdata-pointer after remove() anyhow.
This feature was added to the core with commit
e4a7b9b04d to fix the faulty drivers.

As there is no need anymore to clear the clientdata-pointer, remove all current
occurrences in the drivers to simplify the code and prevent confusion.

When the device is detected, the driver now reports only the left
button as the supported buttons so that X11 driver can detect that
the device is Clickpad. A Clickpad device gives the button events
only as the middle button. The kernel driver morphs to the left
button. The real handling of Clickpad is done rather in X driver

Tejun Heo 5a0e3ad6af include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h
percpu.h is included by sched.h and module.h and thus ends up being
included when building most .c files.  percpu.h includes slab.h which
in turn includes gfp.h making everything defined by the two files
universally available and complicating inclusion dependencies.

percpu.h -> slab.h dependency is about to be removed.  Prepare for
this change by updating users of gfp and slab facilities include those
headers directly instead of assuming availability.  As this conversion
needs to touch large number of source files, the following script is
used as the basis of conversion.

  http://userweb.kernel.org/~tj/misc/slabh-sweep.py

The script does the followings.

* Scan files for gfp and slab usages and update includes such that
  only the necessary includes are there.  ie. if only gfp is used,
  gfp.h, if slab is used, slab.h.

* When the script inserts a new include, it looks at the include
  blocks and try to put the new include such that its order conforms
  to its surrounding.  It's put in the include block which contains
  core kernel includes, in the same order that the rest are ordered -
  alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
  doesn't seem to be any matching order.

* If the script can't find a place to put a new include (mostly
  because the file doesn't have fitting include block), it prints out
  an error message indicating which .h file needs to be added to the
  file.

The conversion was done in the following steps.

1. The initial automatic conversion of all .c files updated slightly
   over 4000 files, deleting around 700 includes and adding ~480 gfp.h
   and ~3000 slab.h inclusions.  The script emitted errors for ~400
   files.

2. Each error was manually checked.  Some didn't need the inclusion,
   some needed manual addition while adding it to implementation .h or
   embedding .c file was more appropriate for others.  This step added
   inclusions to around 150 files.

3. The script was run again and the output was compared to the edits
   from #2 to make sure no file was left behind.

4. Several build tests were done and a couple of problems were fixed.
   e.g. lib/decompress_*.c used malloc/free() wrappers around slab
   APIs requiring slab.h to be added manually.

5. The script was run on all .h files but without automatically
   editing them as sprinkling gfp.h and slab.h inclusions around .h
   files could easily lead to inclusion dependency hell.  Most gfp.h
   inclusion directives were ignored as stuff from gfp.h was usually
   wildly available and often used in preprocessor macros.  Each
   slab.h inclusion directive was examined and added manually as
   necessary.

6. percpu.h was updated not to include slab.h.

7. Build test were done on the following configurations and failures
   were fixed.  CONFIG_GCOV_KERNEL was turned off for all tests (as my
   distributed build env didn't work with gcov compiles) and a few
   more options had to be turned off depending on archs to make things
   build (like ipr on powerpc/64 which failed due to missing writeq).

   * x86 and x86_64 UP and SMP allmodconfig and a custom test config.
   * powerpc and powerpc64 SMP allmodconfig
   * sparc and sparc64 SMP allmodconfig
   * ia64 SMP allmodconfig
   * s390 SMP allmodconfig
   * alpha SMP allmodconfig
   * um on x86_64 SMP allmodconfig

8. percpu.h modifications were reverted so that it could be applied as
   a separate patch and serve as bisection point.

Given the fact that I had only a couple of failures from tests on step
6, I'm fairly confident about the coverage of this conversion patch.
If there is a breakage, it's likely to be something in one of the arch
headers which should be easily discoverable easily on most builds of
the specific arch.

Henrik Rydberg d90e6f6aad Input: bcm5974 - retract efi-broken suspend_resume
With the recent system-wide improvements on suspend/resume and EFI
booting the suspend_resume method of the bcm5974 has broken. When
waking up from the S3 state on the MacBookAir, the trackpad is found
in a yet unknown state, unable to switch to the proper multitouch
mode. The result is a frozen touchpad, and a flood of errors of the
kind

	bcm5974: bad trackpad package, length: 8.

This patch retracts the reset_resume method altogether, falling back
on the generic unbind/rebind functionality of the usb layer until
further investigations can be made as how to reset the device when
booting from efi.

Martin Buck c91ed059a0 Input: ALPS - fix stuck buttons on some touchpads
Enable button release event redirection to the device that got the
button press not only for touchpads with interleaved protocols, but
unconditionally for all Alps touchpads. This is required at least
for the touchpads in Dell Inspiron 8200 and Latitude d630.

Vadim Zaliva 04b4b88cca Input: appletouch - fix integer overflow issue
When reading data from Geyser 2 touchpads used on post Oct 2005 Apple
PowerBooks the driver was casting X and Y coordinates values to
'signed char'. Testing on one of such PowerBooks I have noticed that
touchpad always generates positive values, but some of them are greater
that 127, and thus, when cast to 'signed char' being interpreted as
a negative.

Such bigger values have been observed infrequently, closer to the
edges of a touchpad, so the problem was not very visible.
Nevertheless, the patch would potentially improve touchpad
driver accuracy.

Dmitry Torokhov a9f0c38197 Input: psmouse - make sure we don't schedule reconnects after cleanup
Set state of the device as "initializing" during and after cleanup
to ensure that unsolicited data from the device is not passed on.
We especially want to avoid processing new device announcements
"0xaa 0x00" that can come up before we perform reconnect operation.
