Subject: linux-next: build warnings after merge of the scsi-mkp tree

Hi Martin,

After merging the scsi-mkp tree, today's linux-next build (x86_64
allmodconfig) produced these warnings:

drivers/scsi/myrb.c: In function 'myrb_get_ldev_info':
drivers/scsi/myrb.c:428:10: warning: 'ldev_num' may be used uninitialized in this function [-Wmaybe-uninitialized]
   sdev = scsi_device_lookup(shost, myrb_logical_channel(shost),
          ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
        ldev_num, 0);
        ~~~~~~~~~~~~
drivers/scsi/myrs.c: In function 'myrs_handle_scsi':
drivers/scsi/myrs.c:2175:6: warning: 'status' may be used uninitialized in this function [-Wmaybe-uninitialized]
   if (status == DAC960_V2_AbnormalCompletion &&
      ^
drivers/scsi/myrs.c: In function 'myrs_log_event':
drivers/scsi/myrs.c:988:21: warning: 'cmd_specific' may be used uninitialized in this function [-Wmaybe-uninitialized]
         cmd_specific[0], cmd_specific[1],
