Linus Torvalds 9e1a0aab60 Char/misc fixes for 3.9-rc2
Here are some tiny fixes for the w1 drivers and the final removal patch
 for getting rid of CONFIG_EXPERIMENTAL (all users of it are now gone
 from your tree, this just drops the Kconfig item itself.)
 
 All have been in the linux-next tree for a while.

Arnd Bergmann 037154105e mfd: twl4030-madc: Remove __exit_p annotation
4740f73fe5 "mfd: remove use of __devexit" removed the __devexit annotation
on the twl4030_madc_remove function, but left an __exit_p() present on the
pointer to this function. Using __exit_p was as wrong with the devexit in
place as it is now, but now we get a gcc warning about an unused function.

In order for the twl4030_madc_remove to work correctly in built-in code, we
have to remove the __exit_p.

Tejun Heo 8e467e855c tidspbridge: convert to idr_alloc()
idr_get_new*() and friends are about to be deprecated.  Convert to the
new idr_alloc() interface.

There are some peculiarities and possible bugs in the converted
functions.  This patch preserves those.

* drv_insert_node_res_element() returns -ENOMEM on alloc failure,
  -EFAULT if id space is exhausted.  -EFAULT is at best misleading.

* drv_proc_insert_strm_res_element() is even weirder.  It returns
  -EFAULT if kzalloc() fails, -ENOMEM if idr preloading fails and
  -EPERM if id space is exhausted.  What's going on here?

* drv_proc_insert_strm_res_element() doesn't free *pstrm_res after
  failure.

Only compile tested.

Bill Pemberton 27b351c554 USB: quatech2: only write to the tty if the port is open.
The commit 2e124b4a39 removed the checks
that prevented qt2_process_read_urb() from trying to put chars into
ttys that weren't actually opened.  This resulted in 'tty is NULL'
warnings from flush_to_ldisc() when the device was used.

The devices use just one read urb for all ports.  As a result
qt2_process_read_urb() may be called with the current port set to a
port number that has not been opened.  Add a check if the port is open
before calling tty_flip_buffer_push().

Good job. I was too lazy to bisect for bad commit;)

Reading the code I found problematic kthread_should_stop call from netlink
connector which causes the oops. After applying a patch, I've been testing
owfs+w1 setup for nearly two days and it seems to work very reliable (no
hangs, no memleaks etc).
More detailed description and possible fix is given below:

Function w1_search can be called from either kthread or netlink callback.
While the former works fine, the latter causes oops due to kthread_should_stop
invocation.

This patch adds a check if w1_search is serving netlink command, skipping
kthread_should_stop invocation if so.

Josh Boyer f2b8dfd9e4 serial: 8250: Keep 8250.<xxxx> module options functional after driver rename
With commit 835d844d1 (8250_pnp: do pnp probe before legacy probe), the
8250 driver was renamed to 8250_core.  This means any existing usage of
the 8259.<xxxx> module parameters or as a kernel command line switch is
now broken, as the 8250_core driver doesn't parse options belonging to
something called "8250".

To solve this, we redefine the module options in a dummy function using
a redefined MODULE_PARAM_PREFX when built into the kernel.  In the case
where we're building as a module, we provide an alias to the old 8250
name.  The dummy function prevents compiler errors due to global variable
redefinitions that happen as part of the module_param_ macro expansions.

Sean Young 77e372a3d8 tty/8250_pnp: serial port detection regression since v3.7
The InsydeH2O BIOS (version dated 09/12/2011) has the following in
its pnp resouces for its serial ports:

$ cat /sys/bus/pnp/devices/00:0b/resources
state = active
io disabled
irq disabled

We do not check if the resources are disabled, and create a bogus
ttyS* device. Since commit 835d844d1a (8250_pnp: do pnp probe
before legacy probe) we get a bogus ttyS0, which prevents the legacy
probe from detecting it.

Note, the BIOS can also be upgraded, fixing this problem, but for people
who can't do that, this fix is needed.

Scott Ashcroft d13402a4a9 Fix 4 port and add support for 8 port 'Unknown' PCI serial port cards
I've managed to find an 8 port version of the card 4 port card which was discussed here:

http://marc.info/?l=linux-serial&m=120760744205314&w=2

Looking back at that thread there were two issues in the original patch.

1) The I/O ports for the UARTs are within BAR2 not BAR0. This can been seen in the original post.
2) A serial quirk isn't needed as these cards have no memory in BAR0 which makes pci_plx9050_init just return.

This patch fixes the 4 port support to use BAR2, removes the bogus quirk and adds support for the 8 port card.

Anatolij Gustschin 09081e5b47 tty: serial: mpc5xxx: fix PSC clock name bug
mpc512x platform clock code names PSC clocks as "pscX_mclk" but
the driver tries to get "pscX_clk" clock and this results in

The problem appears when opening ttyPSC devices other than the
system's serial console. Since getting and enabling the PSC clock
fails, uart port startup doesn't succeed and tty flag TTY_IO_ERROR
remains set causing further errors in tty ioctls, i.e.
'strace stty -F /dev/ttyPSC1' shows:

   89c58c1 rtc: rtc-mv: Add support for clk to avoid lockups
   de88747 gpio: mvebu: Add clk support to prevent lockup
   7bf5b40 ARM: kirkwood: fix to retain gbe MAC addresses for DT kernels
   93fff4c ARM: kirkwood: of_serial: fix clock gating by removing clock-frequency
 
 are Cc'd to stable since they were held over from the previous merge window.
 
 The rest are a small collection of fixes and a couple of devicetree conversion
 catchups.

Liu Jinsong d2e0bca377 xen/acpi: remove redundant acpi/acpi_drivers.h include
It's redundant since linux/acpi.h has include it when CONFIG_ACPI enabled,
and when CONFIG_ACPI disabled it will trigger compiling warning

Ian Abbott 564c526a1b staging: comedi: dt9812: use CR_CHAN() for channel number
As pointed out by Dan Carpenper in
<http://driverdev.linuxdriverproject.org/pipermail/devel/2013-February/036025.html>,
the dt9812 comedi driver's use of the `chanspec` member of `struct
comedi_insn` as a channel number is incorrect.  Change it to use
`CR_CHAN(insn->chanspec)` as the channel number (where `insn` is a
pointer to the `struct comedi_insn` being processed).

Geert Uytterhoeven aa1e123482 staging/vt6656: Fix too large integer constant warning on 32-bit
drivers/staging/vt6656/card.c: In function ‘CARDqGetNextTBTT’:
drivers/staging/vt6656/card.c:793: warning: integer constant is too large for ‘unsigned long’ type

Commit c7b7cad0d8 ("staging/vt6656: Fix
sparse warning constant 0xffffffff00000000U is so big it is unsigned long")
changed the constant to "0xffffffff00000000UL", but that only works on
64-bit.  Change it "0xffffffff00000000ULL" to fix it for 32-bit, too.

Philipp Zabel 47b1be5c0f staging: imx/drm: request irq only after adding the crtc
If the bootloader already enabled the display, the interrupt handler
will be called as soon as it is registered. If the CRTC is not already
added at this time, the call to imx_drm_handle_vblank will result in
a NULL pointer dereference.

The patch fixes a kernel panic [1], which has been on linux-next since
Jan 8 [2].
