This patch implements functionality of following ioctl:
SNDRV_TIMER_IOCTL_TREAD - Setting enhanced time read
Sets enhanced time read which is used for reading time with timestamps
and events. The third ioctl's argument is a pointer to an 'int'. Enhanced
reading is set if the third argument is different than 0, otherwise normal
time reading is set.
Implementation notes:
Because the implemented ioctl has 'int' as its third argument, the
implementation was straightforward.
