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.

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>

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.

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.
