[PATCH] fbdev: MIPS supports iomem addresses

From: Kees Cook
Date: Wed Oct 12 2022 - 15:19:03 EST


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
