Jingoo Han 86f6be4fae backlight: ld9040: use devm_ functions
The devm_ functions allocate memory that is released when a driver
detaches.  This patch uses devm_kzalloc of these functions.

Lars-Peter Clausen aa523a82ee blacklight: remove redundant spi driver bus initialization
In ancient times it was necessary to manually initialize the bus field of
an spi_driver to spi_bus_type.  These days this is done in
spi_driver_register() so we can drop the manual assignment.

The patch was generated using the following coccinelle semantic patch:
// <smpl>
@@
identifier _driver;
@@
struct spi_driver _driver = {
	.driver = {
-		.bus = &spi_bus_type,
	},
};
// </smpl>

Donghwa Lee b148a27294 backlight/ld9040.c: regulator control in the driver
This patch supports regulator power control in the driver.  Current ld9040
driver was controlled power on/off sequence by callback function in the
board file.  But, by doing this, there's no need to register lcd power
on/off callback function in the board file.

Paul Gortmaker 355b200bac video: Add module.h to drivers/video files who really use it.
They were getting this implicitly by an include of module.h
from device.h -- but we are going to clean that up and break
that include chain, so include module.h explicitly now.

Axel Lin ef22f6a70c backlight: set backlight type and max_brightness before backlights are registered
Since commit a19a6ee "backlight: Allow properties to be passed at
registration" and commit bb7ca74 "backlight: add backlight type", we can
set backlight type and max_brightness before backlights are registered.
Some newly added drivers did not set it properly, let's fix it.
