Subject: block-qdict: Simplify qdict_flatten_qdict()
X-Git-Tag: qemu-xen-4.12.0-rc1~162^2~12
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=eb0e0f7d3d4a9c585421d05b19ca71df5d69fc47;p=qemu-xen.git

block-qdict: Simplify qdict_flatten_qdict()

There's no need to restart the loop.  We don't elsewhere, e.g. in
qdict_extract_subqdict(), qdict_join() and qemu_opts_absorb_qdict().
Simplify accordingly.
