Subject: [PATCH v2 09/11] lockdep: Fix the way to initialize class_mutex for information of file and line

This patch adds __FILE__ and __LINE__ to arguments passed for
__mutex_init() called in __class_register().
This affects to lockdep_map of class_mutex of struct class_private,
and these will be used to make trace lock events more human friendly.
