Hans de Goede 478b00a623 platform/x86: serdev_helpers: Check for serial_ctrl_uid == NULL
dell_uart_bl_pdev_probe() calls get_serdev_controller() with the
serial_ctrl_uid parameter set to NULL.

In case of errors this NULL parameter then gets passed to pr_err()
as argument matching a "%s" conversion specification. This leads to
compiler warnings when building with "make W=1".

Check serial_ctrl_uid before passing it to pr_err() to avoid these.

Fixes: dc5afd720f ("platform/x86: Add new get_serdev_controller() helper")
