+Subject: HID: amd_sfh: Switch to device-managed dmam_alloc_coherent()
+
+From: Basavaraj Natikar <Basavaraj.Natikar@amd.com>
+
+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)")
