Subject: sdcard: allocate "DriveInfo" to delete the "BlockBackend" automatically
X-Git-Tag: Tizen_Studio_1.3_Release_p2.3.2~40^2~110
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=eee1dfa354097a4ff1f92e57fefa64701fe723a2;p=sdk%2Femulator%2Fqemu.git

sdcard: allocate "DriveInfo" to delete the "BlockBackend" automatically

When the sdcard is detached, "virtio_blk_device_unrealize" marks
auto deletion flag to the "DriveInfo". But "qmp_marshal_input_blockdev_add"
does not create the "DriveInfo". To destroy BlockBackend object automatically
we need to create dummy "DriveInfo".
