Subject: vfio/container: set error on cpr failure
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=36cd81dc139f899127d868ba9baaf3079c336efc;p=thirdparty%2Fqemu.git

vfio/container: set error on cpr failure

Set an error message if vfio_cpr_ram_discard_register_listener fails so
the fail label gets a valid error object.
