nfs: fix do_div() warning by instead using sector_div()
commit 3873d064b8538686bbbd4b858dc8a07db1f7f43a upstream. When compiling a 32bit kernel with CONFIG_LBDAF=n the compiler complains like shown below. Fix this warning by instead using sector_div() which is provided by the kernel.h header file. fs/nfs/blocklayout/extents.c: In function ‘normalize’: include/asm-generic/div64.h:43:28: warning: comparison of distinct pointer types lacks a cast [enabled by default] fs/nfs/blocklayout/extents.c:47:13: note: in expansion of macro ‘do_div’ nfs/blocklayout/extents.c:47:2: warning: right shift count >= width of type [enabled by default] fs/nfs/blocklayout/extents.c:47:2: warning: passing argument 1 of ‘__div64_32’ from incompatible pointer type [enabled by default] include/asm-generic/div64.h:35:17: note: expected ‘uint64_t *’ but argument is of type ‘sector_t *’ extern uint32_t __div64_32(uint64_t *dividend, uint32_t divisor); Signed-off-by: Helge Deller <deller@gmx.de> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
