Subject: [PATCH 4/4] ir-core: remove ir-functions usage from cx231xx
Date: Sat, 24 Apr 2010 23:14:16 +0200	[thread overview]
Message-ID: <20100424211416.11570.83633.stgit@localhost.localdomain> (raw)
In-Reply-To: <20100424210843.11570.82007.stgit@localhost.localdomain>

Convert drivers/media/video/cx231xx/cx231xx-input.c to not
rely on ir-functions.c.

(I do not have the hardware so I can only compile test this)
