Subject: [PATCH 4/4] scripts/coccinelle: require coccinelle >= 1.0.4 on device_node_continue.cocci
Date: Tue, 14 Jun 2016 15:10:17 -0700	[thread overview]
Message-ID: <1465942217-14452-5-git-send-email-mcgrof@kernel.org> (raw)
In-Reply-To: <1465942217-14452-1-git-send-email-mcgrof@kernel.org>

Make use of the new kernel python requirements library to be able to
specify coccinelle binary version requirements. The cocci file
device_node_continue.cocci requires at least coccinelle 1.0.4.
