From 5183cbfbddcf09ecc20b679b2aff4ccc5fd4f3db Mon Sep 17 00:00:00 2001 From: Daire McNamara Date: Fri, 28 Jul 2023 14:13:55 +0100 Subject: [PATCH] PCI: microchip: Correct the DED and SEC interrupt bit offsets [ Upstream commit 6d473a5a26136edf55c435a1c433e52910e03926 ] The SEC and DED interrupt bits are laid out the wrong way round so the SEC interrupt handler attempts to mask, unmask, and clear the DED interrupt and vice versa. Correct the bit offsets so that each interrupt handler operates properly.
