[PATCH v3 3/3] staging: fbtft: access screen buffer directly

In fbtft-bus.c:fbtft_write_vmem16_bus9(), ioread8() is used for accessing the provided screen array. Since screen_buffer actually points to an ordinary buffer, instead access it directly. Signed-off-by: Lars Svensson --- drivers/staging/fbtft/fbtft-bus.c | 8 1 file changed, 4

[PATCH v3 1/3] fb.h: Provide alternate screen_base pointer

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 --- Patch v3: bugfix in fbtft

[PATCH v3 2/3] staging: fbtft: use alternate screen pointer

Member screen_base in struct fb_info is declared with __iomem qualifier causing sparse warnings when used as a regular ponter. To avoid the warnings, instead use alternate non-__iomem pointer, screen_buffer, troughout the driver. Signed-off-by: Lars Svensson --- drivers/staging/fbtft
