[PATCH] powerpc: Loosen udbg_probe_uart_speed sanity checking
The checking of the baudrate in udbg_probe_uart_speed was too tight and would cause reporting back of the default baud rate in cases where the computed speed was valid. Signed-off-by: Kumar Gala <galak@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
