Some drivers use member screen_base of struct fb_info to store non- __iomem pointers, creating the need for ugly __force typecasts to avoid sparse warnings. This adds an alternate pointer without the __iomem qualifyer for this use. Signed-off-by: Lars Svensson <lars1.svensson@sonymobile.com> --- New version of my previous patch, reworked as suggested by Dan Carpenter. For the name of the pointer, "screen_buffer" was the best I could come up with. Other suggestions? //Lars --- include/linux/fb.h | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-)
