Summary
PCI: endpoint: Fix configfs group list head handling
Details

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

PCI: endpoint: Fix configfs group list head handling

Doing a listdel() on the epfgroup field of struct pciepfdriver in pciepfremovecfs() is not correct as this field is a list head, not a list entry. This listdel() call triggers a KASAN warning when an endpoint function driver which has a configfs attribute group is torn down:

================================================================== BUG: KASAN: slab-use-after-free in pciepfremove_cfs+0x17c/0x198 Write of size 8 at addr ffff00010f4a0d80 by task rmmod/319

Remove this incorrect listdel() call from pciepfremovecfs().
