Subject: cmd: dfu: Propagate error if dfu gadget fails
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=5bb624e433ba98cb78d4f3ae5e0e8b6011ea7fce;p=thirdparty%2Fu-boot.git

cmd: dfu: Propagate error if dfu gadget fails

On systems without usb gadget dfu core fails which was reported by error
but command itself returns pass which breaks any usage in a script.
That's why propagate error from run_usb_dnl_gadget().

Fixes: 16297cfb2a20 ("usb: new board-specific USB init interface")
