AMD SFH Driver: Fix memory cleanup via device-managed dmam_alloc_coherent

From this webpage screenshot, we can extract the following key information about the vulnerability: 1. Vulnerability Description: - Vulnerability ID: 4b2c53d93a4b - Vulnerability Type: SFH: Transport Driver to add support of AMD Sensor Fusion Hub (SFH) - Description: AMD Sensor Fusion Hub (SFH) driver adds support for AMD Sensor Fusion Hub (SFH). 2. Testers: - Chris Hixon - Richard - Skyler 3. Reporter: - Chris Hixon 4. Fixers: - Basavaraj Natikar - Jiri Kosina - Greg Kroah-Hartman 5. Fix Details: - HID: amd_sfh: Switch to device-managed dmam_alloc_coherent() - Using the device-managed version simplifies cleanup in the probe() error path. - This device-managed approach ensures proper cleanup, helping to resolve issues such as memory corruption, page faults, btrfs becoming read-only, and btrfs disk corruption. 6. Patch File: - Diff file: drivers/hid/amd-sfh-hid/amd_sfh_client.c - The diff includes the usage of the dmam_alloc_coherent() function. 7. Patch Status: - Already applied to the kernel. This information indicates that the vulnerability is related to the AMD Sensor Fusion Hub (SFH) driver and has been fixed by switching to the device-managed version of dmam_alloc_coherent(). The fix primarily focuses on simplifying cleanup in the probe() error path and ensuring proper cleanup to resolve associated issues.
