'type' is an enum, thus cast of pointer on 64-bit compile test with clang and W=1 causes: wm8994-core.c:625:17: error: cast to smaller integer type 'enum wm8994_type' from 'const void *' [-Werror,-Wvoid-pointer-to-enum-cast] Year ago this was solved, although LKML discussion suggested warning is not suitable for kernel. Nothing changed in this regard for a year, so assume the warning will stay and we want to have warnings-free builds.
