Subject: ALSA: hda - Drop bus->avoid_link_reset flag
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=873ce8ad502cce3ba9295890d52afcce385d4107;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

ALSA: hda - Drop bus->avoid_link_reset flag

Use bus->power_keep_link_on instead.  The controller shouldn't go to
D3 when the link isn't reset, so essentially avoiding the link reset
means avoiding the runtime PM.
