Subject: efi: fix devpath_is_partition()
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=dd1086ac6bda9d464abc9be6a7e24a843b9bf30b;p=u-boot.git

efi: fix devpath_is_partition()

If the path consists only of an end node, it does not refer to a partition.
Avoid returning a random value from the stack in this case.
