Subject: [PATCH 1/2] magicvar: Add magicvar macro with additional name argument
Date: Tue, 15 May 2012 09:07:33 +0200	[thread overview]
Message-ID: <1337065654-17925-2-git-send-email-s.hauer@pengutronix.de> (raw)
In-Reply-To: <1337065654-17925-1-git-send-email-s.hauer@pengutronix.de>

Currently magicvar fails on variables containing a '.' because we can't
use these as C names. Overcome this by adding a new macro which allows
to specify a name seperately.
