From d07ecb4f7070e84de49e8fa4e5a83dd52716d805 Mon Sep 17 00:00:00 2001 From: Peter Chiu Date: Thu, 9 Jan 2025 19:04:36 +0800 Subject: [PATCH] wifi: mt76: mt7996: fix register mapping Bypass the entry when ofs is equal to dev->reg.map[i].size. Without this patch, it would get incorrect register mapping when the CR address is located at the boundary of an entry.
