Input: lm8323 - fix checking PWM interrupt status

INT_PWM1 is already a bitmask, not the bit number, so shifting by INT_PWM1 is
incorrect.

Input: document that unregistering managed devices is not necessary

Apparently some users of managed input devices are confused whether
input_unregister_device() is needed when working with them. Clarify
this in the kernel doc for devm_input_allocate_device(): in most cases
there is no need to call neither input_unregister_device() nor
input_free_device() when working with managed devices.

Input: wacom - fix wacom_set_report retry logic

Logic sets a value and then reads it back to make sure it worked
and retries write on failures.  Since read and write share a buffer,
it needs to be set back up before writing though.

Issue is not seen a lot because 1) it doesn't need to retry for
a lot of tablets and 2) a lot of failures that need a retry are
from an -ETIMEDOUT and hopefully buffer is not touched in this case.

At least one user has shown logs with buffer being modified during
-ETIMEDOUT case with linux 3.7 kernel.

ARM: SAMSUNG: Gracefully exit on suspend failure

As per the Exynos5250 User Manual:
When there are pending interrupt events, WFI/WFE instruction are
ignored. To cancel the power-down sequence follow these steps:
1) Disable system power-down using CENTRAL_SEQ_CONFIGURATION register
2) Clear WAKEUP_STAT register
3) Enable interrupt service routine for CPU

Code for early wakeup for exynos already exists. Remove the panic
on suspend failure, clear the wakeup state register and return 1
from cpu_suspend to indicate a failed suspend (to a user daemon).

Older Samsung SoCs have similar panics and I have removed them all.
Haven't touched the S3C2410 sleep code.

ARM: S3C24XX: let S3C2412_PM select S3C2412_PM_SLEEP

The code to enter sleep is used by both the s3c2412 and s3c2416 and
was thus factored out into an extra config option.

But it seems it was forgotten to add the appropriate select to the
s3c2412 pm option, resulting in breakage when only compiling s3c2412
support.
