[PATCH 6.2 401/663] wifi: mt76: mt7921: fix missing unwind goto in `mt7921u_probe`

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Jiefeng Li <jiefeng_li@xxxxxxxxxxx>

[ Upstream commit 5c47cdebbaeb7724df6f9f46917c93e53f791547 ]

`mt7921u_dma_init` can only return zero or negative number according to its
definition. When it returns non-zero number, there exists an error and this
function should handle this error rather than return directly.
