Subject: scsi: qla2xxx: Pointer may be dereferenced
Patch-mainline: v6.5-rc1
Git-commit: 00eca15319d9ce8c31cdf22f32a3467775423df4
References: bsc#1213747

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.
