Ick, this is still messy, just try making this:

			err |= comedi_check_trigger_arg_min(&cmd->scan_begin_arg,
							    cmd->convert_arg * cmd->chanlist_len);

Yeah, it's over 80 columns, but it looks better and is easier to read,
right?

Also, all your patches have the whitespace turned from tabs into spaces,
making them impossible to be applied even if I wanted to :)

thanks,
