    staging: comedi: drivers: cleanup cmd->flags use · a207c12f
    H Hartley Sweeten authored
    Most of the comedi drivers that support async commands have some sort
    of timer to control the acquisition timing. For these drivers, Step 4
    of the (*do_cmdtest) operations calls a ns_to_timer() function that
    converts the desired ns time of the command into a value used to set
    the timer. These ns_to_timer() functions also typically pass the
    cmd->flags in order to determine the desired rounding mode.
    Some of the drivers mask the cmd->flags with TRIG_ROUND_MASK when
    calling the ns_to_timer() functions. Move all the masking into the
    ns_to_timer() functions and just pass the cmd->flags directly.
    The cmd->flags member is an unsigned int, change the parameter type
    in the the ns_to_timer() functions to match.
    For aesthetics, rename the parameter in all the ns_to_timer()
    functions to 'flags'.
