X-Git-Tag: v5.15~307^2~8
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=424e531b47f83da87490464c5bf633dfb624fe6a;p=platform%2Fkernel%2Flinux-starfive.git

ALSA: hda/cs8409: Ensure Type Detection is only run on startup when necessary

Type Detection should only be run after init and when the controls have been
built. There is no need to run it multiple times.
