earlycon: initialise baud field of earlycon device structure
For now baud field of earlycon structure device is't initialised at all in of_setup_earlycon (in oppositе to register_earlycon). So when I use stdout-path to point earlycon device (like stdout-path = &serial or stdout-path = "serial:115200n8") baud field of earlycon device structure remains uninitialised and earlycon initialization is not performed correctly as of_setup_earlycon is used. When pass all arguments via bootargs (like bootargs = "earlycon=uart8250,mmio32,0xf0005000,115200n8") initialization is performed correctly as register_earlycon is used. So initialise baud field of earlycon device structure by value of "current-speed" property from device tree or from options (if they exist) when we use of_setup_earlycon Signed-off-by: Eugeniy Paltsev <Eugeniy.Paltsev@synopsys.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
