From a9e064c00413fb59e7236be81578024ab0ebe6b2 Mon Sep 17 00:00:00 2001 From: "Luis R. Rodriguez" Date: Wed, 29 Jun 2016 15:14:57 -0700 Subject: coccicheck: add support for requring a coccinelle version Enable Coccinelle SmPL patches to require a specific version of Coccinelle. In the event that the version does not match we just inform the user, if the user asked to go through all SmPL patches we just inform them of the need for a new version of coccinelle for the SmPL patch and continue on with the rest. This uses the simple kernel scripts/ld-version.sh to create a weight on the version provided by spatch. The -dirty attribute is ignored if supplied, the benefit of scripts/ld-version.sh is it has a long history and well tested.
