5.15-stable review patch. If anyone has any objections, please let me know. ------------------ From: Linus Walleij [ Upstream commit 1dd85662fee6e2ac580b1c4f9a0c0a7ae6e31f0e ] The RX overrun interrupt is reported in interrupt status register 4, but gmac_irq() acknowledges it using the RX descriptor error bit from status register 0. For GMAC0 this writes the GMAC1 overrun bit, while for GMAC1 the shift leaves no bit in the 32-bit register. Acknowledge the same per-port RX overrun bit that was detected.
