From 0a0b5f4b43671f8f128eb438edacee0a1d113385 Mon Sep 17 00:00:00 2001 From: Heiner Kallweit Date: Tue, 30 Mar 2021 12:43:18 -0500 Subject: ARM: iop32x: disable N2100 PCI parity reporting MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit On the N2100, instead of just marking the r8169 chips as having broken_parity_status, disable parity error reporting for them entirely. This was the only relevant place that set broken_parity_status, so we no longer need to check for it in the r8169 error interrupt handler.
