From: Arnd Bergmann <arnd@xxxxxxxx>
Calling a function through an incompatible pointer type causes breaks
kcfi, so clang warns about the assignment:
drivers/gpu/drm/nouveau/nvkm/subdev/bios/shadowof.c:73:10: error: cast from 'void (*)(const void *)' to 'void (*)(void *)' converts to incompatible function type [-Werror,-Wcast-function-type-strict]
73 | .fini = (void(*)(void *))kfree,
Avoid this with a trivial wrapper.
Fixes: c39f472e9f14 ("drm/nouveau: remove symlinks, move core/ to nvkm/ (no code changes)")
