Subject: [PATCH 0/2] livepatch: Fix usage of kobject_init_and_add()

Hi,

Currently there are a few places in kernel/livepatch/ which do not
correctly use kobject_init_and_add().

An error return from kobject_init_and_add() requires a call to
kobject_put().

The cleanup function after a successful call to kobject_init_and_add()
is kobject_del(). 

This set is part of an effort to check/fix all callsites of
kobject_init_and_add().

This set fixes all callsites under kernel/livepatch/

thanks,
Tobin.
