Subject: scsi-generic: Simplify error handling code
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=c6caae553c65475009dc18fdae0c89a1a1d7b427;p=qemu.git

scsi-generic: Simplify error handling code

Coverity doesn't like the ignored return value introduced in
9d3b155186c278 (hw/block: Fix the return type), and other callers are
converted already in ceff3e1f01.

This one was added lately in d9bcd6f7f23a and missed the train. Do it
now.
