NAME
       clamp_val - return a value clamped to a given range using val's type

SYNOPSIS
       clamp_val(val, min, max);

ARGUMENTS
       val
	   current value

       min
	   minimum allowable value

       max
	   maximum allowable value

DESCRIPTION
       This macro does no typechecking and uses temporary variables of
       whatever type the input argument 'val' is. This is useful when val is
       an unsigned type and min and max are literals that will otherwise be
       assigned a signed integer type.
