Nit: I'd suggest something like rtlgen_decode_speed() as it's decoding the register value to a speed. > The function would then always return 0, so change it to void. > > Signed-off-by: Eric Woudstra <ericwouds@gmail.com> Reviewed-by: Russell King (Oracle) <rmk+kernel@armlinux.org.uk> Thanks!

The value of the register to determine the speed, is retrieved differently when using Clause 45 only. To use the rtlgen_get_speed() function in this case, pass the value of the register as argument to rtlgen_get_speed(). The function would then always return 0, so change it to void.
