Changes in V2: - Add patch to allocate port->rx_fifo buffer in probe to resolve NULL pointer dereference crash reported by stephen. The crash is caused due to set_termios call starting RX engine and RX engine is sampling some garbage data from line, and by the time startup is called, we have few data to read but port->rx_fifo buffer is not allocated causing NULL pointer dereference. Changes in V3: - As per Stephen's comment, change the declaration of rx_fifo pointer from u32 to void. satya priya (2): tty: serial: qcom_geni_serial: Allocate port->rx_fifo buffer in probe tty: serial: qcom_geni_serial: Fix RX cancel command failure drivers/tty/serial/qcom_geni_serial.c | 37 ++++++++++++++++++++++------------- 1 file changed, 23 insertions(+), 14 deletions(-) -- QUALCOMM INDIA, on behalf of Qualcomm Innovation Center, Inc. is a member of Code Aurora Forum, hosted by The Linux Foundation
