Subject: ecryptfs: remove unnecessary mux from ecryptfs_init_ecryptfs_miscdev()
From: Michael Halcrow <mhalcrow@xxxxxxxxxx>
The misc_mtx should provide all the protection required to keep the daemon
hash table sane during miscdev registration. Since this mutex is causing
gratuitous lockdep warnings, this patch removes it.
