Pramod Gurav 254af0a3c7 Input: mpr121 - switch to using managed resources
This change switches the driver to use devm_* managed resources APIs to
request the resources in probe to simplify probe error path and module
unloading and does away with remove function.

Paul Gortmaker bf9a9f8e51 Input: delete non-required instances of include <linux/init.h>
None of these files are actually using any __init type directives
and hence don't need to include <linux/init.h>.  Most are just a
left over from __devinit and __cpuinit removal, or simply due to
code getting copied from one driver to the next.

Jingoo Han c838cb3d47 Input: use dev_get_platdata()
Use the wrapper function for retrieving the platform data instead
of accessing dev->platform_data directly. This is a cosmetic change
to make the code simpler and enhance the readability.

CONFIG_HOTPLUG is going away as an option so __devexit is no
longer needed.

Lars-Peter Clausen 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.

Axel Lin 1b92c1cf6b Input: convert I2C drivers to use module_i2c_driver()
This patch converts the drivers in drivers/input/* to use the
module_i2c_driver() macro which makes the code smaller and a bit
simpler.

Jiejing Zhang c7b4a5d58b Input: mpr121 - improve sensibility of touch key
The Quick Charge bit in Electrode conf register should be set in init
function. This bit was missed in chip's document, which may cause touch
controller charge too slow to generate an interrupt.

Also, adjust the default vlaue of touch and release threshold
to make touch key more sensitive, this fix touch may not sensitive
after setup with plastic case.
