binder: fix pointer cast warning
commit 9a0a930fe2535a76ad70d3f43caeccf0d86a3009 upstream. binder_uintptr_t is not the same as uintptr_t, so converting it into a pointer requires a second cast: drivers/android/binder.c: In function 'binder_translate_fd_array': drivers/android/binder.c:2511:28: error: cast to pointer from integer of different size [-Werror=int-to-pointer-cast] 2511 | sender_ufda_base = (void __user *)sender_uparent->buffer + fda->parent_offset; | ^ Fixes: 656e01f3ab54 ("binder: read pre-translated fds from sender buffer") Acked-by: Todd Kjos <tkjos@google.com> Acked-by: Randy Dunlap <rdunlap@infradead.org> # build-tested Acked-by: Christian Brauner <christian.brauner@ubuntu.com> Signed-off-by: Arnd Bergmann <arnd@arndb.de> Link: https://lore.kernel.org/r/20211207122448.1185769-1-arnd@kernel.org Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Signed-off-by: Carlos Llamas <cmllamas@google.com> Signed-off-by: Lee Jones <lee@kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
