Subject: [PATCH] fbdev: MIPS supports iomem addresses
Date:   Wed, 12 Oct 2022 12:18:54 -0700
Message-Id: <20221012191838.never.778-kees@kernel.org>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

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
