[PATCH 6.4 282/292] scsi: qla2xxx: Avoid fcport pointer dereference

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

 



From: Nilesh Javali <njavali@xxxxxxxxxxx>

commit 6b504d06976fe4a61cc05dedc68b84fadb397f77 upstream.

Klocwork reported warning of NULL pointer may be dereferenced.  The routine
exits when sa_ctl is NULL and fcport is allocated after the exit call thus
causing NULL fcport pointer to dereference at the time of exit.

To avoid fcport pointer dereference, exit the routine when sa_ctl is NULL.
