Subject: [PATCH 5.19 395/717] tty: xilinx_uartps: Fix the ignore_status

From: Shubhrajyoti Datta <shubhrajyoti.datta@...inx.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")
