[PATCH 5.4 063/168] ALSA: hda/realtek - Enable the headset of ASUS B9450FA with ALC294

[Greg Kroah-Hartman]

From: Jian-Hong Pan <jian-hong@xxxxxxxxxxxx>

commit 8b33a134a9cc2a501f8fc731d91caef39237d495 upstream.

A headset on the laptop like ASUS B9450FA does not work, until quirk
ALC294_FIXUP_ASUS_HPE is applied.
