ALSA: korg1212: Add __force annotation to cast in user-copy callbacks
The user-copy callbacks in korg1212 driver contain the explicit cast from a user pointer to a kernel pointer, but they missed __force prefix. It's mandatory for converting between them. Spotted by sparse, a warning like: sound/pci/korg1212/korg1212.c:1329:33: warning: cast removes address space of expression Signed-off-by: Takashi Iwai <tiwai@suse.de>
