There is no need to init .owner field.
Based on the patch from Peter Griffin
"mmc: remove .owner field for drivers using module_platform_driver"This patch removes the superflous .owner field for drivers which
use the module_platform_driver API, as this is overriden in
platform_driver_register anyway."Signed-off-by: Michal Simek

The various devm_ functions allocate memory that is released when a
driver detaches. This patch uses these functions for data that is
allocated in the probe function of a platform device and is only freed
in the remove function. Also, the unnecessary labels are removed and
linux/device.h is added to make sure the devm_*() routine declarations
are unambiguously available.The initial call to platform_get_resource is moved down to the
introduced call to devm_ioremap_resource that uses its result.Signed-off-by: Himangi Saraogi

This patch introduces the use of devm_kzalloc and does away with the
kfrees in the probe and remove functions. Also, a label and the err
variable are removed. The header device.h is included to make the devm_
function explicitly available and slab.h is done away with as it is no
longer needed.Signed-off-by: Himangi Saraogi

Update extcon for v3.18
This patchset add new extcon provider driver and fix minor issue of extcon driver.
Detailed description for patchset:
1. Add new Richtek RT8973A extcon driver
This driver support for Richtek RT8973A which is Micro USB Switch OVP and
i2c interface. The RT8973A is a USB port accessory detector and switch that is
optimized to protect low voltage system from abnormal high input voltage
(up to 28V) and supports high speed USB operation. Also, RT8973A support
'auto-configuration' mode. If auto-configuration mode is enabled, RT8973A
would control internal h/w patch for USB D-/D+ switching.2. Fix code cleanup for other extcon driver
- extcon-sm5502 driver
: Fix bug to check cable type and build break.
: Move header file from include/linux/extcon to drivers/extcon because this
header file is only user for extcon-sm5502.c.
: Clean up codes by using checkpatch script
- extcon-max77693 driver
: Use resource managed interrupt function
: Fix bug to set ADC debounce time
- extcon-gpio driver
: Fix minor code cleanup

When it writes some value other than 0 to BTLDset and JIGset, muic device
will be reset automatically. And it happens during updating ADC debounce time,
because it shares same register. To update ADC debounce time without reset,
set value only to ADCDbset and 0 to BTLDset and JIGset.Signed-off-by: Jonghwa Lee
