Subject: [PATCH 1/6] platform/x86/tuxedo: Don't use device driver data
Date: Tue, 28 Jul 2026 13:59:16 +0200	[thread overview]
Message-ID: <20260728115918.125349-2-aer@tuxedocomputers.com> (raw)
In-Reply-To: <20260728115918.125349-1-aer@tuxedocomputers.com>

The WMI driver for TUXEDO Sirius devices used to rely on the device
driver data through dev_set_drvdata even though it is only a virtual
low level HID driver. For this purpose, it is better to use the
driver_data of the hid_device struct to avoid interfering with high
level device drivers.
