[PATCH 5.15 130/206] octeontx2-pf: Add check for devm_kcalloc

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

 



From: Jiasheng Jiang <jiasheng@xxxxxxxxxxx>

[ Upstream commit cd07eadd5147ffdae11b6fd28b77a3872f2a2484 ]

As the devm_kcalloc may return NULL pointer,
it should be better to add check for the return
value, as same as the others.
