< /* peam rms level structure like we get from hardware 
<   
<    maybe in future we can memory map it so I just copy it
<    to user on ioctl call now an dont change anything
<    rms are made out of low and high values
<    where (long) ????_rms = (????_rms_l >> 8) + ((????_rms_h &
0xFFFFFF00)<<24)
<    (i asume so from the code)
