From mboxrd@z Thu Jan 1 00:00:00 1970 From: nicolas.ferre@atmel.com (Nicolas Ferre) Date: Wed, 3 Mar 2010 15:17:35 +0100 Subject: [PATCH] mmc: at91_mci: correct kunmap_atomic() In-Reply-To: <20100302133434.761df661.akpm@linux-foundation.org> References: <20100302133434.761df661.akpm@linux-foundation.org> Message-ID: <1267625855-32695-1-git-send-email-nicolas.ferre@atmel.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org kunmap_atomic() accepts a pointer to any location in the page so we do not need the subtraction and cast. Signed-off-by: Nicolas Ferre --- Andrew, I created a new patch that you can stack at the top of the previous patch series. I guess that you cannot fold it in other patches as the kunmap_atomic() correction impacts two different patches.
