Pull backlight updates from Lee Jones:
 "New Functionality:
   - Add support for an enable GPIO; lm3630a_bl
   - Add support for short circuit handling; qcom-wled
   - Add support for automatic string detection; qcom-wled

  Fix-ups:
   - Update Device Tree bindings; lm3630a-backlight, led-backlight,
     qcom-wled
   - Constify; ipaq_micro_bl
   - Optimise for CPU cycles; pwm_bl
   - Coding style fix-ups; pwm_bl
   - Trivial fix-ups (white space, comments, renaming); pwm_bl,
     gpio_backlight, qcom-wled
   - Kconfig dependency hacking; LCD_HP700
   - Rename, refactor and add peripherals; pm8941-wled => qcom-wled
   - Make use of GPIO look-up tables; tosa_bl, tosa_lcd
   - Remove superfluous code; gpio_backlight
   - Adapt GPIO direction handling; gpio_backlight
   - Remove legacy use of platform data; gpio_backlight

  Bug Fixes:
   - Provide modules aliases; lm3630a_bl"
