Bug description:
To fix this bug, B/OEM-B/C needs only 1 patch, while v5.0-rc1 introduced
a new patch which affect this issue, so the DISCO needs 2 patches.
[Impact]
After S3, some codecs (alc236, alc255, alc891 and some HDMI codec) stop
working, they can't detect jack plugging/unplugging or the audio device
can't show up in the gnome-sound-setting
[Fix]
After S3, if it runs runtime_resume(), the codec works again. We change
the driver to let system_resume() trigger runtime_resume()
[Test Case]
This issue is reported from OEM project, some codecs can't detect
jack pluggin/unplugging, some codecs can't show up in the UI, after
applying this patch, all related bugs are fixed.
[Regression Potential]
Low. have tested on many machines (with this issue or without this issue),
all worked well.
