Subject: checkpatch.pl: Add warning for new __packed additions
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=f503cc49a570b1e28a93b75bc912aedc93ba2cd0;p=project%2Fbcm63xx%2Fu-boot.git

checkpatch.pl: Add warning for new __packed additions

While there are valid reasons to use __packed, often the answer is that
you should be doing something else here instead.
