Subject: Revert "hda_intel suspend latency: shorten codec read"
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d238998fbfa49f30b02f0a5de5294ca53c58348c;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

Revert "hda_intel suspend latency: shorten codec read"

This reverts commit 57a04513cb35086d54bcb2cb92e6627fc8fa0fae.

Harald Dunkel reports that it broke sound for him:
  "Alsa stopped working for me.  I still can access /dev/dsp, change the
   volume and so on, but the speakers are quiet."

Reverting it fixed things for him.
