Because the address we got in fact is DMA or bus address for the platform. This patch also fixes below build warning: drivers/video/fbdev/ocfb.c:335:2: warning: passing argument 3 of ‘dma_alloc_attrs’ from incompatible pointer type [enabled by default] Signed-off-by: Qiang Chen --- drivers/video/fbdev/ocfb.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/video/fbdev/ocfb.c b/drivers/video/fbdev/ocfb.c index 7f9dc9b..de98196 100644 --- a/drivers/video/fbdev/ocfb.c +++ b/drivers/video/fbdev/ocfb.c @@ -61,7 +61,7 @@ struct ocfb_dev { /* flag indicating whether the regs are little endian accessed */ int little_endian; /* Physical and virtual addresses of framebuffer */ - phys_addr_t fb_phys; + dma_addr_t fb_phys; void __iomem *fb_virt; u32 pseudo_palette[PALETTE_SIZE]; }; -- 1.8.2.2
