6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Basavaraj Natikar <Basavaraj.Natikar@xxxxxxx>
commit c56f9ecb7fb6a3a90079c19eb4c8daf3bbf514b3 upstream.
Using the device-managed version allows to simplify clean-up in probe()
error path.
Additionally, this device-managed ensures proper cleanup, which helps to
resolve memory errors, page faults, btrfs going read-only, and btrfs
disk corruption.
Fixes: 4b2c53d93a4b ("SFH:Transport Driver to add support of AMD Sensor Fusion Hub (SFH)")
