Subject: [PATCH 2/5] net/niu: Fix none-const BUILD_BUG_ON usage
Date: Mon, 01 Sep 2008 16:11:24 +0300 [thread overview]
Message-ID: <48BBE9FC.9080702@panasas.com> (raw)
In-Reply-To: <48BBE77D.7070007@panasas.com>
It would be easy to constify the expression but I have removed
the BUILD_BUG_ON. (Left the useful comment though). Since
it has no point here, a BUILD_BUG_ON is used when two
inter-dependent but separate pieces of code must match. which
is not the case here.
