Subject: [PATCH] [TRIVIAL] FIX: unintended variable name reuse

From: Jan-Simon Möller <dl9pf@....de>

The variable name events_group is already in used and led to a compilation error
when using clang to build the Linux Kernel . The fix is just to rename the var.
No functional change. Please apply.

Fix suggested in discussion by PaX Team <pageexec@...email.hu>
Signed-off-by: Jan-Simon Möller <dl9pf@....de>
