From: Vincent Whitchurch <vincent.whitchurch@axis.com>
commit 51a08bdeca27988a17c87b87d8e64ffecbd2a172 upstream.
The exit function is wrongly placed in the __init section and this leads to a crash when the module is unloaded. Just remove both the init and exit functions since this module does not need them.
