Fabio Estevam a7cfaf165e serial: serial_core: Perform NULL checks for release/request_port ops ... Doing the following UART bind/unbind sequence on a i.mx platform causes a kernel crash due to NULL pointer dereference: echo 21f4000.serial > /sys/bus/platform/drivers/imx-uart/bind echo 21f4000.serial > /sys/bus/platform/drivers/imx-uart/unbind Fix this problem by adding NULL checks prior to calling release/request_port ops.
