Subject: [PATCH V3 05/12] dmaengine/dw_dmac: Don't use magic number for total number of channels
Date: Wed, 1 Feb 2012 16:12:21 +0530	[thread overview]
Message-ID: <42b0936c114afb25ae50b34ecd3302ef86ea4190.1328091915.git.viresh.kumar@st.com> (raw)
In-Reply-To: <cover.1328091915.git.viresh.kumar@st.com>

Total number of channels is passed in pdata->nr_channels variable, thus we must
not use magic number '7' for total number of channels.
