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.

A few new i2c-drivers came into the kernel which clear the

will do it.

c53252b780 backlight: fix module alias prefix for adp8870_bl
This is an i2c driver, not a platform driver, thus use "i2c" prefix for
the module alias.
