Kim, Milo 313bf0b1a0 leds: lm355x, lm3642: support camera LED triggers for flash and torch
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.

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

G.Shark Jeong b98d13c725 leds: Add new LED driver for lm355x chips
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)
