Most of these are simple tests to see if the argument "is" a value, a "min" value, or a "max" value. Each of these tests then clamps the argument to the value if it fails the test. Introduce three new helper functions in comedi_fc.h to handle these tests and remove the boilerplate code from the drivers. The new helper functions are: cfc_check_trigger_arg_is() - argument must be == the value cfc_check_trigger_arg_min() - argument must be >= the value cfc_check_trigger_arg_max() - argument must be <= the value All of these helpers set the argument to the value and return -EINVAL if the validation fails.
