Subject: [PATCH] mt76: mt7921: fix retrying release semaphore without end
Git-commit: 02d1c7d494d8052288bc175e4ff54b56d08a3c5f
Patch-mainline: v5.16-rc1
References: git-fixes stable-5.14.19
We should pass the error code to the caller immediately
to avoid the possible infinite retry to release the semaphore.
Fixes: 1c099ab44727 ("mt76: mt7921: add MCU support")
