Add MIPS to fb_* helpers list for iomem addresses. This silences Sparse warnings about lacking __iomem address space casts: drivers/video/fbdev/pvr2fb.c:800:9: sparse: sparse: incorrect type in argument 1 (different address spaces) drivers/video/fbdev/pvr2fb.c:800:9: sparse: expected void const * drivers/video/fbdev/pvr2fb.c:800:9: sparse: got char [noderef] __iomem *screen_base Reported-by: kernel test robot <lkp@intel.com> Link: https://lore.kernel.org/lkml/202210100209.tR2Iqbqk-lkp@intel.com/ Cc: Helge Deller <deller@gmx.de> Cc: linux-fbdev@vger.kernel.org Cc: dri-devel@lists.freedesktop.org Signed-off-by: Kees Cook <keescook@chromium.org> --- include/linux/fb.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
