5eb02c01bd drivers/video/backlight/adp88?0_bl.c: fix resume 
Clearing the NSTBY bit in the control register also automatically clears
the BLEN bit.  So we need to make sure to set it again during resume,
otherwise the backlight will stay off.

91cdb23990 backlight: adp8870: use devm_ functions 
The devm_ functions allocate memory that is released when a driver
detaches.  This patch uses devm_kzalloc of these functions.

36c3e75907 drivers/video/backlight/adp88x0_bl.c: fix bit testing logic 
We need to write new value if the bit mask fields of new value is not
equal to old value.  It does not make sense to write new value only when
all the bit_mask bits are zero.

2967b0ad33 video/backlight: remove obsolete cleanup for clientdata 
A few new i2c-drivers came into the kernel which clear the
clientdata-pointer on exit or error.  This is obsolete meanwhile, the core
will do it.
