2014-01-27leds: leds-mc13783: Remove unneeded mc13xxx_{un}lockAlexander Shiyan
LED registers are used only in this driver, so no additional locking is needed. Read-Modify-Write cycle in workqueue is already protected by regmap. Signed-off-by: Alexander Shiyan <shc_work@mail.ru> Signed-off-by: Bryan Wu <cooloney@gmail.com>
2014-01-27leds: leds-mc13783: Remove duplicate field in platform dataAlexander Shiyan
LED platform data are overwhelmed by excessive field "max_cur" which just replicates few bits of "led_control" field. This patch removes this field and adds a definition for the current settings in the header. Signed-off-by: Alexander Shiyan <shc_work@mail.ru> Signed-off-by: Bryan Wu <cooloney@gmail.com>

2013-06-20leds: leds-mc13783: remove unnecessary platform_set_drvdata()Jingoo Han
The driver core clears the driver data to NULL after device_release or on probe failure, since commit 0998d0631001288a5974afc0b2a5f568bcdecb4d (device-core: Ensure drvdata = NULL when no driver is bound). Thus, it is not needed to manually clear the device driver data to NULL. Signed-off-by: Jingoo Han <jg1.han@samsung.com> Signed-off-by: Bryan Wu <cooloney@gmail.com>

2012-05-29leds: Use kcalloc instead of kzalloc to allocate arrayThomas Meyer
The advantage of kcalloc is that will prevent integer overflows which could result from the multiplication of number of elements and size and it is also a bit nicer to read.

2011-05-26mfd: Use mfd cell platform_data for mc13xxx cells platform bitsSamuel Ortiz
With the addition of a platform device mfd_cell pointer, MFD drivers can go back to passing platform data back to their sub drivers. This allows for an mfd_cell->mfd_data removal and thus keep the sub drivers MFD agnostic. This is mostly needed for non MFD aware sub drivers.

2011-03-23mfd: mfd_cell is now implicitly available to mc13xxx driversAndres Salomon
The cell's platform_data is now accessed with a helper function; change clients to use that, and remove the now-unused data_size. Note that mfd-core no longer makes a copy of platform_data, but the mc13xxx-core driver creates the pdata structures on the stack. In order to get around that, the various ARM mach types that set the pdata have been changed to hold the variable in static (global) memory. Also note that __initdata references in aforementioned pdata structs have been dropped. Signed-off-by: Andres Salomon <dilinger@queued.net> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
