Hi all,

After merging the hid tree, today's linux-next build (i386 defconfig)
failed like this:

drivers/hid/hidraw.c: In function 'hidraw_send_report':
drivers/hid/hidraw.c:143:63: error: cast from pointer to integer of different size [-Werror=pointer-to-int-cast]
  143 |                 ret = __hid_hw_output_report(dev, buf, count, (__u64)file, false);
      |                                                               ^
