Subject: [PATCH 10/11] io.h: update definitions of __raw_{read,write}*
Date: Tue, 16 Feb 2010 15:46:25 +0100	[thread overview]
Message-ID: <1266331586-11253-11-git-send-email-mkl@pengutronix.de> (raw)
In-Reply-To: <1266331586-11253-10-git-send-email-mkl@pengutronix.de>

This patch updates the definitions of the __raw_read and __raw_write
functions so that "sparse" doesn't complain.
