The probe function correct passes a dma_addr_t pointer into dma_alloc_coherent(), but has a cast to resource_size_t, which might be different from dma_addr_t:
drivers/video/fbdev/da8xx-fb.c: In function 'fb_probe': drivers/video/fbdev/da8xx-fb.c:1431:10: error: passing argument 3 of 'dma_alloc_coherent' from incompatible pointer type [-Werror=incompatible-pointer-types] This removes the cast, which avoids the warning.
