[PATCH 5.1 073/115] scsi: myrs: Fix uninitialized variable

From: Greg Kroah-Hartman
Date: Mon Jun 17 2019 - 17:26:46 EST

[ Upstream commit 41552199b5518fe26bee0829a28dd1880441b430 ]

drivers/scsi/myrs.c: In function 'myrs_log_event':
drivers/scsi/myrs.c:821:24: warning: 'sshdr.sense_key' may be used uninitialized in this function [-Wmaybe-uninitialized]
struct scsi_sense_hdr sshdr;

If ev->ev_code is not 0x1C, sshdr.sense_key may be used uninitialized. Fix
this by initializing variable 'sshdr' to 0.
