Linus Torvalds b5c78e04dd Staging tree update for 3.9-rc1
Here's the big staging tree merge for 3.9-rc1
 
 Lots of cleanups and updates for drivers all through the staging tree.
 We are pretty much "code neutral" here, adding just about as many lines
 as we removed.
 
 All of these have been in linux-next for a while.

Linus Torvalds 06991c28f3 Driver core patches for 3.9-rc1
Here is the big driver core merge for 3.9-rc1
 
 There are two major series here, both of which touch lots of drivers all
 over the kernel, and will cause you some merge conflicts:
   - add a new function called devm_ioremap_resource() to properly be
     able to check return values.
   - remove CONFIG_EXPERIMENTAL
 
 If you need me to provide a merged tree to handle these resolutions,
 please let me know.
 
 Other than those patches, there's not much here, some minor fixes and
 updates.

Linus Torvalds 5a1203914a - Four new drivers:
o goldfish_battery:
     This is Android Emulator battery driver. Originally from Google, but
     Intel folks reshaped it for mainline;
 
   o pm2301_charger:
     A new driver for ST-Ericsson 2301 Power Management chip, uses AB8500
     battery management core;
 
   o qnap-poweroff:
     The driver adds poweroff functionality for QNAP NAS boxes;
 
   o restart-poweroff:
     A generic driver that implements 'power off by restarting'. The actual
     poweroff functionality is implemented through a bootloader, so Linux'
     task is just to restart the box. The driver is useful on Buffalo
     Linkstation LS-XHL and LS-CHLv2 boards. Andrew Lunn worked on
     submitting the driver (as well as qnap-poweroff above).
 
 - A lot of fixes for ab8500 drivers. This is a part of efforts of syncing
   internal ST-Ericsson development tree with the mainline. Lee Jones @
   Linaro worked on compilation and reshaping these series;
 
 - New health properties for the power supplies: "Watchdog timer expire"
   and "Safety timer expire";
 
 - As usual, a bunch of fixes/cleanups here and there.

Dan Carpenter 64d26f225f generic-adc-battery: Fix forever loop in gab_remove()
There is a forever loop calling iio_channel_release() because the
"chan < " part of the "chan < ARRAY_SIZE()" is missing.  This is in both
the error handling on probe and also in the remove function.

The other thing is that it's possible for some of the elements of the
adc_bat->channel[chan] array to be an ERR_PTR().  I've changed them to be
NULL instead.  We're still not allowed to pass NULLs to
iio_channel_release() so I've added a check.

Finally, I removed an unused "chan = ARRAY_SIZE(gab_chan_name);" statement
as a small cleanup.

Michał Mirosław 9f3b795a62 driver-core: constify data for class_find_device()
All in-kernel users of class_find_device() don't really need mutable
data for match callback.

In two places (kernel/power/suspend_test.c, drivers/scsi/osd/osd_uld.c)
this patch changes match callbacks to use const search data.

The const is propagated to rtc_class_open() and power_supply_get_by_name()
parameters.

Note that there's a dev reference leak in suspend_test.c that's not
touched in this patch.

Power supply subsystem creates thermal zone device for the property

before 'ab8500 battery temperature monitor' driver is initialized. ab8500
btemp driver is initialized with subsys_initcall whereas thermal subsystem
is initialized with fs_initcall which causes
thermal_zone_device_register(...) to crash since the required structure
'thermal_class' is not initialized yet:

Paer-Olof Haakansson 34c11a709e u8500-charger: Delay for USB enumeration
If charging is started before USB enumeration of an Accessory
Charger Adapter has finished, the AB8500 will generate a
VBUS_ERROR. This in turn results in timeouts and delays the
enumeration with around 15 seconds. This patch delays the
charging and then ramps currents slowly to avoid VBUS errors.
The delay allows the enumeration to have finished before
charging is turned on.

When the charging safety timer elapses, the battery health is
shown as "Good". This is misleading and also makes it difficult
to distinguish issues relating to discharging despite the fact
that the charger is still connected.

When in actual fact a safety timer elapse is an indication of a
fault in the battery. Here we make this clearer by reporting
POWER_SUPPLY_HEALTH_UNSPEC_FAILURE instead.
