Subject: [PATCH 6.6 504/638] ALSA: hda/tas2781: configure the amp after firmware load

From: Gergo Koteles <soyer@....hu>

[ Upstream commit 68f7f3ff6c2a0998be9dc07622bd0d16fd1fda20 ]

Make the amp available immediately after a module
load to avoid having to wait for a PCM hook action.
(eg. unloading & loading the module while listening
music)
