* [media] adv7604: Replace *_and_or() functions with *_clr_set()Laurent Pinchart2014-05-25
| | | | | | | | | | | | | The *_and_or() functions take an 'and' bitmask to be ANDed with the register value before ORing it with th 'or' bitmask. As the functions are used to mask and set bits selectively, this requires the caller to invert the 'and' bitmask and is thus error prone. Replace those functions with a *_clr_set() variant that takes a mask of bits to be cleared instead of a mask of bits to be kept.
