From 7f852de0003219c431a6f2ffd951fd82a4673660 Mon Sep 17 00:00:00 2001 From: Baochen Qiang Date: Mon, 12 Jan 2026 15:36:24 +0800 Subject: [PATCH] wifi: ath12k: fix preferred hardware mode calculation For single pdev device like WCN7850/QCC2072, preferred_hw_mode is initialized to WMI_HOST_HW_MODE_SINGLE. Later when firmware sends supported modes to host, each mode is compared with the initial one and if the priority of the new mode is higher, update the parameter and store mode capability. For WCN7850, this does not result in issue, as one of the supported mode indeed has a higher priority. However the only available mode of QCC2072 at this stage is WMI_HOST_HW_MODE_SINGLE, which fails the comparison, hence mode capability is not stored. Subsequently driver initialization fails. Fix it by accepting a mode with the same priority.
