[ALSA] timers: add module refcounting for global timers
Modules: RTC timer driver,Timer Midlevel Add a module pointer to the timer structure and use it for refcounting instead of the card's module pointer to prevent the global timer modules (rtctimer and hpetimer) from being removed while in use. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
