Use the wrapper function for retrieving the platform data instead of
accessing dev->platform_data directly.

LM355x and LM3642 support flash and torch functionality.
(Camera driver) (LED trigger for camera) (LED driver)
Turn on the flash ...> ledtrig_flash_ctrl(true) ...> LM355x or LM3642
brightness ctrl
<actual driving here>
Flash/torch LEDs are controlled by other driver using LED camera trigger
APIs, ledtrig_flash_ctrl()/ledtrig_torch_ctrl().
Then, actual device control is activated by each LED driver such like
LM355x or LM3642.

We don't need the sysfs file to be world writable or group writable.
This file is write-only, change it to S_IWUSR (0200).

This driver is a general version for LM355x,lm3554 and lm3556,led chips of TI.
LM3554 :
The LM3554 is a 2 MHz fixed-frequency synchronous boost
converter with 1.2A dual high side led drivers.
Datasheet: www.ti.com/lit/ds/symlink/lm3554.pdf
LM3556 :
The LM3556 is a 4 MHz fixed-frequency synchronous boost
converter plus 1.5A constant current driver for a high-current white LED.
Datasheet: www.national.com/ds/LM/LM3556.pdf
(bryan.wu@canonical.com: use flush_work() to replace flush_work_sync() which is
deprecated)
