staging: tidspbridge: remove dev_init() and dev_exit()
The dev module has a dev_init() and a dev_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>
