Subject: block: Suppress unhelpful extra errors in bdrv_img_create()
X-Git-Tag: v2.3.0-rc0~45^2~8
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=6be4194b9215ed29f258543ce34a1b4b2003864d;p=thirdparty%2Fqemu.git

block: Suppress unhelpful extra errors in bdrv_img_create()

bdrv_img_create() uses qemu_opt_set(), which reports errors with
qerror_report_err().  Its error messages aren't helpful here, the
caller reports one that actually makes sense.  I don't know how to
trigger the error conditions, though.

Switch to qemu_opt_set_err() to get rid of the unwanted messages.
