Subject: [PATCH 1/3] ARM i.MX28: fix bit operation
Date: Fri, 21 Jan 2011 11:57:52 +0100 [thread overview]
Message-ID: <1295607474-6559-2-git-send-email-s.hauer@pengutronix.de> (raw)
In-Reply-To: <1295607474-6559-1-git-send-email-s.hauer@pengutronix.de>
reg | (1 << clk->enable_shift) always evaluates to true. Switch it
to & which makes much more sense
