Subject: [PATCH] fb: update cdev map_base
Date: Fri, 14 Jan 2011 20:48:44 +0100 [thread overview]
Message-ID: <1295034524-18722-2-git-send-email-s.hauer@pengutronix.de> (raw)
In-Reply-To: <1295034524-18722-1-git-send-email-s.hauer@pengutronix.de>
Calling fb_activate_var potentially changes the framebuffer address,
so we have to update the fb0 cdev afterwards.
