ALSA: hda - Fix jack detection at resume with VT codecs (6b6d0007) · Commits · 戴 / test

VT202x codecs seem requiring some delay after the resume D0 power transition for making the jack detection working again. Without the delay soon after D0, the jack is always detected as unplugged. Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=98921 Signed-off-by:
