From: Uwe Kleine-König Date: Mon, 8 Feb 2010 20:07:16 +0000 (+0100) Subject: arm/imx/gpio: remove a BUG_ON in hot path X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=6574305b0ed32f286dcebd653a2f3ba4e421f06c;p=linux.git arm/imx/gpio: remove a BUG_ON in hot path Now if the problem occurs that triggered the BUG_ON before, the machine runs in a NULL pointer dereference. So it wouldn't be much harder now to debug the situation if it occured.
