fbtft uses fb_info's screen_base field to store a non-__iomem allocation. Cast away the __iomem qualifier when freeing the pointer to suppress the sparse warning. Fixes the following sparse warnings: drivers/staging/fbtft/fbtft-core.c:918:19: warning: incorrect type in argument 1 (different address spaces) drivers/staging/fbtft/fbtft-core.c:918:19: expected void const *addr drivers/staging/fbtft/fbtft-core.c:918:19: got char [noderef] <asn:2>*screen_base Signed-off-by: Garret Kelly <gdk@xxxxxxxxxx> --- drivers/staging/fbtft/fbtft-core.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/staging/fbtft/fbtft-core.c b/drivers/staging/fbtft/fbtft-core.c index 37dcf7e..1196dda 100644 --- a/drivers/staging/fbtft/fbtft-core.c +++ b/drivers/staging/fbtft/fbtft-core.c @@ -925,7 +925,7 @@ EXPORT_SYMBOL(fbtft_framebuffer_alloc); void fbtft_framebuffer_release(struct fb_info *info) { fb_deferred_io_cleanup(info); - vfree(info->screen_base); + vfree((void __force *)info->screen_base); framebuffer_release(info); } EXPORT_SYMBOL(fbtft_framebuffer_release); -- 2.0.2 _______________________________________________ devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxx http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
