[Qemu-devel] [PATCH 14/14] block: Add missing bdrv_delete() for SG_IO BlockDriver in find_image_format()

[Kevin Wolf]

From: Nicholas A. Bellinger <address@hidden>

This patch adds a missing bdrv_delete() call in find_image_format() so that a
SG_IO BlockDriver properly releases the temporary BlockDriverState *bs created
from bdrv_file_open()
