Pull backlight updates from Lee Jones:
"This set is comprised of a couple of small but important fixes and a
number of clean-up and refactoring patches. The fixes correct an EPROM
address for the LP8556 and improve memory allocation safety in the LED
backlight driver.

The remainder of the set is made up of refactoring work to the mp3309c
driver and a series of patches to make a number of drivers more
self-contained by including their own dependencies.

Improvements & Fixes:
- Correct the EPROM start address for the LP8556 to align with the
device's datasheet.
- Use devm_kcalloc() in the LED backlight driver for safer array
allocation with overflow protection.

Cleanups & Refactoring
- Drop an unnecessary call to pwm_apply_args() in the mp3309c driver.
- Modernize struct initialization in the mp3309c driver by using a
compound literal instead of memset.
- Make numerous drivers self-contained by including necessary headers
directly rather than relying on transitive includes from the core
backlight header"
