4.9-stable review patch. If anyone has any objections, please let me know.
------------------ From: Bill Kuzeja <[email protected]> commit 5f7c2beef819d9ea2d1b814edf6f5981420e9cf8 upstream. After a Qlogic card breaks when initializing (test case), the system can crash in qla2xxx_eh_abort if processing anything but a scsi command type srb.
