Subject: sandbox: Check the filename in jump_to_image_no_args()
X-Git-Url: http://git.dujemihanovic.xyz/img/sics.gif?a=commitdiff_plain;h=12efc933b9e69f7340703655d84b9b610fa42fd4;p=u-boot.git

sandbox: Check the filename in jump_to_image_no_args()

If the filename is NULL this function currently crashes. Update it to fail
gracefully.
