3dde22a98e Input: bcm5974 - Add support for 2012 MacBook Pro Retina

9b7e31bbf4 Input: request threaded-only IRQs with IRQF_ONESHOT
Since commit 1c6c69525b ("genirq: Reject bogus threaded irq requests")
threaded IRQs without a primary handler need to be requested with
IRQF_ONESHOT, otherwise the request will fail. This patch adds the
IRQF_ONESHOT to input drivers where it is missing. Not modified by
this patch are those drivers where the requested IRQ will always be a
nested IRQ (e.g. because it's part of an MFD), since for this special
case IRQF_ONESHOT is not required to be specified when requesting the
IRQ.

rep_data is not an array anymore, so taking it's address when passing to
wacom_get_report() is wrong.

Keymaps used by drivers based on matrix-keymap facilities are arrays of
unsigned shorts, not chars. Treating them otherwise produces corrupted
keymaps.

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.

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.

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.

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.

71f3d070a3 Input: tc3589x-keypad - remove unnecessary checks
settle_time and debounce_period are u8 and thus can not be greater than
TC3589x_MAX_DEBOUNCE_SETTLE which is 255.

There also no need to mask out nibbles form board->krow and board->kcol
as we validate that they are in correct range.

commit 7968a5dd49
Input: synaptics - add support for Relative mode

Accidentally broke support for advanced gestures (multitouch)
on some trackpads such as the one in my ThinkPad X220 by
incorretly changing the condition for enabling them. This
restores it.

8eaeb93933 mfd: Convert twl6040 to i2c driver, and separate it from twl core
Complete the separation of the twl6040 from the twl core since
it is a separate chip, not part of the twl6030 PMIC.

Make the needed Kconfig changes for the depending drivers at the
same time to avoid breaking the kernel build (vibra, ASoC components).

0e3d0f3d96 Input: da9052 - fix memory leak in da9052_onkey_probe()
If, in drivers/input/misc/da9052_onkey.c::da9052_onkey_probe(), the
call to either kzalloc() or input_allocate_device() fails then we will
return -ENOMEM from the function without freeing the other allocation
that may have succeeded, thus we leak either the memory allocated for
'onkey' or the memory allocated for 'input_dev' if one succeeds and
the other fails.
Fix that by jumping to the 'err_free_mem' label at the end of the
function that properly cleans up rather than returning directly.
