Subject: [PATCH] sr: Fix a recently introduced W=1 compiler warning
Date: Sun, 29 Mar 2020 19:53:04 -0700	[thread overview]
Message-ID: <20200330025304.10743-1-bvanassche@acm.org> (raw)

Fix the following compiler warning:

drivers/scsi/sr.c:686:12: warning: initialized field overwritten [-Woverride-init]
  686 |  .ioctl  = sr_block_compat_ioctl,
      |            ^~~~~~~~~~~~~~~~~~~~~
drivers/scsi/sr.c:686:12: note: (near initialization for 'sr_bdops.ioctl')

Cc: Arnd Bergmann <arnd@arndb.de>
Fixes: d320a9551e39 ("compat_ioctl: scsi: move ioctl handling into drivers")
