ALSA: hda - More strict correction of invalid pinctl bits
Check more strictly about the validity of pinctl values in snd_hda_set_pin_ctl() and correct the wrong bits automatically. Also provide the helper function to correct pinctl bits to codec drivers. This automatically fixes the invalid pinctl writes that are found in a few Realtek fixups for NID 0x0f amp like ASUS A6Rp. Signed-off-by: Takashi Iwai <tiwai@suse.de>
