[ Upstream commit 0affdba22aca5573f9d989bcb1d71d32a6a03efe ]
clang-16 warns about casting between incompatible function types:
drivers/gpu/drm/nouveau/nvkm/subdev/bios/shadow.c:161:10: error: cast from 'void (*)(const struct firmware *)' to 'void (*)(void *)' converts to incompatible function type [-Werror,-Wcast-function-type-strict] 161 | .fini = (void(*)(void *))release_firmware,
This one was done to use the generic shadow_fw_release() function as a callback for struct nvbios_source. Change it to use the same prototype as the other five instances, with a trivial helper function that actually calls release_firmware.
