Subject: [PATCHv2 2/2] x86: Match bitops prototypes

Building VirtualBox modules causes type mismatch complaints when
mixing void * and unsigned long *.
Adjust bitops function prototypes in asm-generic/bitops/le.h
to match the generic ones in arch/x86/include/asm/le.h
That is, replace void* with unsigned long *

Cc: <stable@...r.kernel.org> # v4.9+
