staging: tidspbridge: remove msg_mod_init() and msg_exit()
The msg module has a msg_mod_init() and a msg_exit() whose only purpose is to keep a reference counting which is not used at all. This patch removes these functions and the reference count variable. There is no functional changes. Signed-off-by: Víctor Manuel Jáquez Leal <vjaquez@igalia.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
