ALSA: timer: catch invalid timer object creation A timer object for the classes SNDRV_TIMER_CLASS_CARD and SNDRV_TIMER_CLASS_PCM has to be associated with a card object, but we have no check at creation time. Such a timer object with NULL card causes various unexpected problems, e.g. NULL dereference at reading the sound timer proc file. So as preventive measure while the creating the sound timer object is created the card information availability is checked for the mentioned entries and returned error if its NULL.
