[alsa-devel] [PATCH v2 2/2] ALSA: hda - change the pintbl to undef tbl for Dell with alc289

[Hui Wang]

We have another Dell laptop which needs the DELL4_MIC_NO_PRESENCE,
and this laptop has different pincfg definitions from existing
ones in the pintbl, rather adding a new entry, let us change
the exiting tbl to undef tbl. It will cover all Dell laptops
with alc289 codec and the pins of 0x19 and 0x1b are undef by default.
