[PATCH 4.4 72/86] ALSA: hda/realtek - Limit int mic boost for Thinkpad T530
From: Greg Kroah-Hartman
Date: Mon May 18 2020 - 14:30:26 EST
From: Takashi Iwai <tiwai@xxxxxxx>
commit b590b38ca305d6d7902ec7c4f7e273e0069f3bcc upstream.
Lenovo Thinkpad T530 seems to have a sensitive internal mic capture
that needs to limit the mic boost like a few other Thinkpad models.
Although we may change the quirk for ALC269_FIXUP_LENOVO_DOCK, this
hits way too many other laptop models, so let's add a new fixup model
that limits the internal mic boost on top of the existing quirk and
apply to only T530.
