In the Linux kernel, the following vulnerability has been resolved:
HID: amd_sfh: Fix memory leak in amd_sfh_work
Kmemleak tool detected a memory leak in the amd_sfh driver.
====================

====================
The fix is to freeing request_list entry once the processed entry is
removed from the request_list.
