pwm caching needs to be dropped as well. It is no longer initialized in
max6639_init_client(), but updated and later used in pwm_store() and
pwm_show(). Looking at the datasheet, the pwm registers are volatile
and should not be cached in the first place.
Yes. I did that but found that the register is write only. i.e.,
Odd. The datasheet says that it is r/w or, rather, that reading it returns
the _current_ pwm value and writing it sets the target pwm value in pwm mode.
What happens when the register is read ?
