[PATCH v2 12/13] backports: remove extra BACKPORT_ prefix from kernel versioning

Luis R. Rodriguez
2014-11-05T03:19:43Z

From: "Luis R. Rodriguez" <mcgrof@suse.com>

The CPTCFG_ prefix already implies backport, when integration
is used we'd end up with a double BACKPORT_ prefix, so just
remove the existing one as its not needed.
