Subject: [PATCH] staging: comedi: das16m1: use comedi_fc helpers to validate
 timer args

Use the comedi_fc helper cfc_check_trigger_arg_is() to validate the
trigger arguments when the source is TRIG_TIMER.

For aesthetics, rename the local variable 'tmp' to 'arg'.

Also, change the 'err' variable to the correct type.
