Hello,

I try to use the checkpatch.pl script on drivers/nvidia/nv_backlight.c but 
before this I tried to compile the code with make nv_backlight.o I get the 
following error:

nv_backlight.c:12:29: fatal error: linux/backlight.h: No such file or 
directory
compilation terminated.

The backlight.h file does not exist. What to do?
