Re: [PATCH] rocker: fix harmless warning on 32-bit machines

The rocker driver tries to assign a pointer to a 64-bit integer
and then back to a pointer. This is safe on all architectures,
but causes a compiler warning when pointers are shorter than
64-bit:

rocker/rocker.c: In function 'rocker_desc_cookie_ptr_get':
rocker/rocker.c:809:9: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
  return (void *) desc_info->desc->cookie;
         ^

This adds another cast to uintptr_t to tell the compiler
that it's safe.

Applied to net-next, thanks.
