Subject: fwu: print a message if empty capsule checks fail
X-Git-Url: http://git.dujemihanovic.xyz/%22/img/sics.gif/%22/static/git-favicon.png?a=commitdiff_plain;h=6f933aa963bb971d848ff6bd1c743035bbc98ead;p=u-boot.git

fwu: print a message if empty capsule checks fail

When dealing with processing of the empty capsule, the capsule gets
applied only when the checks for the empty capsule pass. Print a
message to highlight if empty capsule checks fail, and return an error
value, similar to the normal capsules.
