[PATCH 097/524] Staging: cxt1e1: remove all code dependent on LINUX_VERSION_CODE

Greg Kroah-Hartman gregkh at suse.de
Thu Aug 5 22:18:00 UTC 2010


From: Jiri Kosina <jkosina at suse.cz>

Remove all code which is dead for in-kernel driver due to being
ifdefed by LINUX_VERSION_CODE.

While at it, also remove surrounding code which is commented out,
or '#if 1' nops.
