[ Upstream commit 185fdb4697cc9684a02f2fab0530ecdd0c2f15d4 ]
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.
