[PATCH 5.4 089/194] scsi: fnic: Return error if vmalloc() failed

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

 



5.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Artem Chernyshev <artem.chernyshev@xxxxxxxxxxx>

[ Upstream commit f5f27a332a14f43463aa0075efa3a0c662c0f4a8 ]

In fnic_init_module() exists redundant check for return value from
fnic_debugfs_init(), because at moment it only can return zero. It make
sense to process theoretical vmalloc() failure.

Found by Linux Verification Center (linuxtesting.org) with SVACE.

Fixes: 9730ddfb123d ("scsi: fnic: remove redundant assignment of variable rc")
