6dc463511d Input: wacom - Bamboo One 1024 pressure fix 
Bamboo One's with ID of 0x6a and 0x6b were added with correct
indication of 1024 pressure levels but the Graphire packet routine
was only looking at 9 bits.  Increased to 10 bits.

This bug caused these devices to roll over to zero pressure at half
way mark.

The other devices using this routine only support 256 or 512 range
and look to fix unused bits at zero.

b7af2bb84c Input: wacom - battery reporting improvements 
Do not register battery device until connected to a tablet.
This prevents an empty battery icon from being shown when tablet is
connected using USB cable.

Also, call power_supply_powers() for apps that can make use of that
info.

And stop ignoring input registration failures.

Subject: [PATCH] Input: omap-keypad: dynamically handle register offsets

Keypad controller register offsets are different for omap4
and omap5. Handle these offsets through static mapping and
assign these mappings during run time.

Tested on omap4430 sdp with 3.4-rc3.
Tested on omap5430evm with 3.1-custom kernel.

3b7e09fad9 Input: ALPS - add semi-MT support for v4 protocol 
This patch adds semi-MT support for ALPS v4 protocol touchpads.
It is based on the work by Seth Forshee for ALPS v3 and v4 protocol
support. Three packets are required to assemble and process the MT
data. ST events are reported at once to avoid latency. If there
were two contacts or more, report MT data instead of ST events.

Thanks to Seth Forshee for providing most of the code, guidance
and insight for producing this patch.

46f49b7a22 Input: serio_raw - signal EFAULT even if read/write partially succeeds 
When copy_to/from_user fails in the middle of transfer we should not
report to the user that read/write partially succeeded but rather
report -EFAULT right away, so that application will know that it got
its buffers all wrong.

If application messed up its buffers we can't trust the data fetched
from userspace and successfully written to the device or if data read
from the device and transferred to userspace ended up where application
expected it to end.

If serio_write() fails we still going to report partial writes if failure
happens in the middle of the transfer.

34604086be Input: lpc32xx_ts - fix device tree compatible string 
During the device tree integration of the various LPC32xx drivers,
we agreed on using non-wildcard "compatible" strings. This change
switches lpc32xx_ts touchscreen driver to use "nxp,lpc3220-tsc".

This patch converts the drivers in drivers/input/* to use module_pci_driver()
macro which makes the code smaller and a bit simpler.

The major fixes here are:
   * Build fix for omap_hsmmc with OF against 3.4-rc1.
   * Fix CONFIG_MMC_UNSAFE_RESUME semantics regression against 3.3,
     which broke hotplug card detection when UNSAFE_RESUME is set.

   * Fix two libertas SDIO-powered-resume regressions.
  Also small fixes for discard/sanitize, dw_mmc, cd-gpio and esdhc-imx.

486c8aba39 Input: serio_raw - ensure we don't block in non-blocking read 
Avoid calling wait_event_interruptible() if client requested non-blocking
read, since it is not guaranteed that another thread will not consume
event after we checked if serio_raw->head != serio_raw->tail.

Also ensure we do not return 0 but keep waiting instead in blocking case,
when another thread steals "our" byte.
