Geert Uytterhoeven d717ea73e3 pwm: Fix period and polarity in pwm_get() for non-perfect matches ... If pwm_get() finds a look-up entry with a perfect match (both dev_id and con_id match), the loop is aborted, and "p" still points to the correct struct pwm_lookup. If only an entry with a matching dev_id or con_id is found, the loop terminates after traversing the whole list, and "p" now points to arbitrary memory, not part of the pwm_lookup list. Then pwm_set_period() and pwm_set_polarity() will set random values for period resp. polarity. To fix this, save period and polarity when finding a new best match, just like is done for chip (for the provider) and index. This fixes the LCD backlight on r8a7740/armadillo-legacy, which was fed period 0 and polarity -1068821144 instead of 33333 resp. 1.
