    Subject[PATCH 5.15 285/530] tty: xilinx_uartps: Fix the ignore_status
    Date
    From: Shubhrajyoti Datta <shubhrajyoti.datta@xilinx.com>

    [ Upstream commit b8a6c3b3d4654fba19881cc77da61eac29f57cae ]

    Currently the ignore_status is not considered in the isr.
    Add a check to add the ignore_status.

    Fixes: 61ec9016988f ("tty/serial: add support for Xilinx PS UART")
