Subject: [PATCH 6/8 v3] i2c: i801: drop ENABLE_INT9
Date: Wed, 27 Jun 2012 21:54:13 +0800	[thread overview]
Message-ID: <1340805255-8041-7-git-send-email-djkurtz@chromium.org> (raw)
In-Reply-To: <1340805255-8041-1-git-send-email-djkurtz@chromium.org>

Later patches enable interrupts.  This preliminary patch removes the older
unsupported ENABLE_INT9 flag.
