Subject: [Qemu-devel] [PULL 1/6] block: m25p80: sync_page(): Deindent function body.
Date: Mon, 23 Jun 2014 17:31:14 +0800 [thread overview]
Message-ID: <1403515879-14359-2-git-send-email-stefanha@redhat.com> (raw)
In-Reply-To: <1403515879-14359-1-git-send-email-stefanha@redhat.com>
From: Peter Crosthwaite <peter.crosthwaite@xilinx.com>
sync_page() was conditionalizing it's whole fn body on the bdrv being
non-null. Just return for the function immediately on NULL brdv and
get rid of the big if.
Makes implementation consistent with flash_zynq_area().
