staging: comedi: comedi_fc: introduce cfc_check_trigger_is_unique
"Step 2" of each do_cmdtest checks that the trigger sources are
unique by doing something like this for each trigger:
if (cmd->start_src != TRIG_TIMER &&
cmd->start_src != TRIG_FOLLOW &&
cmd->start_src != TRIG_EXT)
err++;
/* Test the remaining triggers similarly */
if (err)
return 2;
Introduce a helper function in comedi_fc to handle this boilerplate.
The drivers can then just do:
err |= cfc_check_trigger_is_unique(cmd->start_src);
/* Test the remaining triggers similarly */
if (err)
return 2;
