[PATCH v2 0/2] ALSA: hda: Widget memory fixes

From: Evan Green
Date: Wed Jun 26 2019 - 17:22:45 EST

This series fixes concurrency issues with the sysfs widget array. The first
function patches up the locking that was introduced recently to protect more
of the data structure. The second patch fixes a race between a reinit and the
initial population of the array which could result in a length and array
getting out of sync.

Changes in v2:
- Introduced widget_mutex relocation

Evan Green (2):
ALSA: hda: Fix widget_mutex incomplete protection
ALSA: hda: Use correct start/count for sysfs init
