[Qemu-devel] [PATCH for-2.9] block/curl: Prefer URL in options over filename

[Max Reitz]

Currently, the curl block driver will replace any URL specified through
the options QDict by a filename, if one has been given. However, the
options QDict should generally take precedence, which is implemented by
this patch.

Not really critical, so getting this into 2.9 is sufficient.
