Subject: [PATCH 07/11] wifi: ath12k: fix endianness handling in QMI bdf download
Date: Wed, 16 Jul 2025 09:50:56 +0200	[thread overview]
Message-ID: <20250716075100.1447352-8-alexander.wilhelm@westermo.com> (raw)
In-Reply-To: <20250716075100.1447352-1-alexander.wilhelm@westermo.com>

Ensure proper endianness support for big-endian platforms by correcting
data types in the QMI board data file download request message. Add
missing byte swaps wherever this structure is accessed or modified.

Fixes: d889913205cf ("wifi: ath12k: driver for Qualcomm Wi-Fi 7 devices")
