What it is

In the Linux kernel, the following vulnerability has been resolved:

HID: amd_sfh: Fix potential NULL pointer dereference

devm_add_action_or_reset() can suddenly invoke amd_mp2_pci_remove() at

registration that will cause NULL pointer dereference since

corresponding data is not initialized yet. The patch moves

initialization of data before devm_add_action_or_reset().

Found by Linux Driver Verification project (linuxtesting.org).
