[alsa-devel] [PATCH] ALSA: hda - Clean up jackpoll_ms option handling
Currently the jackpoll_ms option value is passed indirectly by referring to an array in chip->jackpoll_ms although each card needs to see only the assigned value. Also, the sanity check is done at each time in get_jackpoll_interval() although basically jackpoll_ms option is a read-only, hence we need to evaluate only once at probe time.
This patch is the code simplification about the above points: the jack polling interval is directly set to chip->jackpoll_interval so that it can be simply copied to each codec.
No functional change but only code reduction.
