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.
