Subject: mt76: mt7921: fix retrying release semaphore without end
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=68acaaf117a9976fedbf13e00f39d7503df09b12;p=linux.git

mt76: mt7921: fix retrying release semaphore without end

[ Upstream commit 02d1c7d494d8052288bc175e4ff54b56d08a3c5f ]

We should pass the error code to the caller immediately
to avoid the possible infinite retry to release the semaphore.
