Has anyone checked whether this has any impact for the BE > ARM platforms? Probably not. I can't say anything to that matter, but I wonder if this patch is just going around the problem that we get sparse warnings when falling into the else ifdef block in fb.h. The macros in the else block are defined as: #define fb_readb(addr) (*(volatile u8 *) (addr)) And fb code passes a pointer to __iomem. So shouldn't the cast be to (volatile u8 __iomem *)? Tomi
