Subject: [PATCH 08/18] dmaengine/amba-pl08x: No need to check "ch->signal < 0"
Date: Fri, 29 Jul 2011 16:19:18 +0530	[thread overview]
Message-ID: <1e1f287888a2ce9affdcbded8f63028fa3f6b09b.1311936524.git.viresh.kumar@st.com> (raw)
In-Reply-To: <cover.1311936523.git.viresh.kumar@st.com>

We have just executed following in pl08x_get_phy_channel():
	ch->signal = -1;

We don't have to compare "ch->signal < 0", as this will always be true.
