Subject: [PATCH] kni: bug fix in module_init and module_exit
 unregister_XXX should be called when module exits or error occurs
 during module init, but register_XXX is called in case that
 HAVE_SIMPLIFIED_PERNET_OPERATIONS is not set.

Patch content is good, thanks for the fix, but patch doesn't apply
cleanly (leading spaces are missing)
Also in commit log, Signed-off-by and Fixes tags are missing.

And commit log can be simpler, something like:
"Fix pernet calls when HAVE_SIMPLIFIED_PERNET_OPERATIONS is not set."

Would you mind sending a new version of the patch?

Thanks,
ferruh
