Subject: [PATCH] checkpatch: Don't test for prefer ether_addr_<foo>
Date: Wed, 31 Aug 2016 10:48:59 -0700 [thread overview]
Message-ID: <dc32ec66d24647f4cdf824c8dfbbc59aa7ce7b7d.1472665676.git.joe@perches.com> (raw)
< sigh > Comment these tests out.
These are just too enticing to people that don't verify that
both source and dest addresses really must be __aligned(2).
It helps make Dan Carpenter happy too.
