Subject: [PATCH] binfmt_em86: Fix incompatible pointer type

From: Daniel Wagner <daniel.wagner@...-carit.de>

Since the -Wincompatible-pointer-types is reported as error, alpha
doesn't build anymore. Let's fix it in a minimal way.

fs/binfmt_em86.c:73:35: error: passing argument 2 of ‘copy_strings_kernel’ from incompatible pointer type [-Werror=incompatible-pointer-types]
   retval = copy_strings_kernel(1, &i_arg, bprm);
                                   ^            ^
fs/binfmt_em86.c:77:34: error: passing argument 2 of ‘copy_strings_kernel’ from incompatible pointer type [-Werror=incompatible-pointer-types]
  retval = copy_strings_kernel(1, &i_name, bprm);
                                  ^
