Jan Kara bd8d7cf5b8 printk: fix lockdep instrumentation of console_sem ... Printk calls mutex_acquire() / mutex_release() by hand to instrument lockdep about console_sem. However in some corner cases the instrumentation is missing. Fix the problem by creating helper functions for locking / unlocking console_sem which take care of lockdep instrumentation as well.
