Subject: [PATCH] hiddev: compat_ptr() returns a void *

so cast it to unsigned long before passing it to hiddev_ioctl.

This gets rid of:

drivers/hid/usbhid/hiddev.c: In function 'hiddev_compat_ioctl':
drivers/hid/usbhid/hiddev.c:746: warning: passing argument 4 of 'hiddev_ioctl' makes integer from pointer without a cast
