[PATCH 3/3] media: hfi_venus: Request interrupt for sync cmds
From: Stanimir Varbanov
Date: Thu Nov 19 2020 - 19:11:17 EST
From: Vikash Garodia <vgarodia@xxxxxxxxxxxxxx>
For synchronous commands, update the message queue variable.
This would inform video firmware to raise interrupt on host
CPU whenever there is a response for such commands.
