Subject: [Qemu-devel] [PULL 2/4] xen-block: remove redundant assignment
Date: Thu, 28 Feb 2019 17:34:37 +0000	[thread overview]
Message-ID: <20190228173439.8013-3-anthony.perard@citrix.com> (raw)
In-Reply-To: <20190228173439.8013-1-anthony.perard@citrix.com>

From: Paul Durrant <paul.durrant@citrix.com>

The assignment to 'p' is unnecessary as the code will either goto 'invalid'
or p will get overwritten.
