Subject: [PATCH] arm: mx28: fix bit operation in clock setting
Date: Sat, 10 Sep 2011 12:26:07 +0200 [thread overview]
Message-ID: <1315650367-3371-1-git-send-email-w.sang@pengutronix.de> (raw)
reg | (1 << clk->enable_shift) always evaluates to true. Switch it
to & which makes much more sense. Same fix as 13be9f00 (ARM i.MX28: fix
bit operation) at a different location.
