From 377cbdc9271613f559b8879b10ec6ea9c7cafaed Mon Sep 17 00:00:00 2001 From: Jeremy Pallotta Date: Thu, 23 Dec 2021 17:23:29 -0800 Subject: [PATCH] ntb_hw_switchtec: Fix pff ioread to read into mmio_part_cfg_all [ Upstream commit 32c3d375b0ed84b6acb51ae5ebef35ff0d649d85 ] Array mmio_part_cfg_all holds the partition configuration of all partitions, with partition number as index. Fix this by reading into mmio_part_cfg_all for pff.
