ALSA: sc6000: Use explicit cast for __iomem pointer
The recent optimization to store an iomem pointer in card's private_data field caused sparse warnings. Although they are practically harmless, add the explicit cast for avoiding the spurious warnings. Fixes: 9b7843d1e125 ("ALSA: sc6000: Assign vport directly on card's private_data") Reported-by: kernel test robot <lkp@intel.com> Link: https://lore.kernel.org/r/202107210511.SnFqlZMa-lkp@intel.com Link: https://lore.kernel.org/r/20210720224902.7169-1-tiwai@suse.de Signed-off-by: Takashi Iwai <tiwai@suse.de>
