[PATCH] Toshiba driver cleanup
Toshiba legacy driver cleanup: - use module_init/module_exit for initialization instead of using #ifdef MODULE and calling tosh_init manually from drivers/char/misc.c - do not explicitly initialize static variables - some whitespace and formatting cleanups Signed-off-by: Dmitry Torokhov <dtor@mail.ru> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
