stable inclusion from linux-4.19.198 commit 2e98a83f55b461a20dcaca5f6e0a7104eaf5008d
--------------------------------
[ Upstream commit 466ba3c8ff4fae39e455ff8d080b3d5503302765 ]
The driver defined of_device_id table but did not use it with of_match_table. This prevents usual matching via devicetree and causes a W=1 warning:
drivers/reset/reset-a10sr.c:111:34: warning: ‘a10sr_reset_of_match’ defined but not used [-Wunused-const-variable=]
