From: Frederic Weisbecker <fweisbec@xxxxxxxxx>
Subject: kmod: bunch of internal functions renames
Underscores on function names aren't much verbose to explain the purpose
of a function. And kmod has interesting such flavours.
Lets rename the following functions:
* __call_usermodehelper -> call_usermodehelper_exec_work
* ____call_usermodehelper -> call_usermodehelper_exec_async
* wait_for_helper -> call_usermodehelper_exec_sync
