Subject: scsi: qla2xxx: Pointer may be dereferenced
From: Shreyas Deodhar <sdeodhar@xxxxxxxxxxx>
commit 00eca15319d9ce8c31cdf22f32a3467775423df4 upstream.
Klocwork tool reported pointer 'rport' returned from call to function
fc_bsg_to_rport() may be NULL and will be dereferenced.
Add a fix to validate rport before dereferencing.
