staging: xgifb: vb_init: use readl()/writel() to access iomapped memory
Use readl() and writel() in FB memory test instead of direct pointer access, and also add iomem annotations for the FB memory. The patch eliminates the following sparse warnings: drivers/staging/xgifb/XGI_main_26.c:2113:69: warning: incorrect type in assignment (different address spaces) drivers/staging/xgifb/XGI_main_26.c:2113:69: expected unsigned char *static [addressable] [toplevel] [assigned] pjVideoMemoryAddress drivers/staging/xgifb/XGI_main_26.c:2113:69: got void [noderef] <asn:2>* drivers/staging/xgifb/XGI_main_26.c:2399:30: warning: incorrect type in assignment (different address spaces) drivers/staging/xgifb/XGI_main_26.c:2399:30: expected char [noderef] <asn:2>*screen_base drivers/staging/xgifb/XGI_main_26.c:2399:30: got char *[addressable] [toplevel] [assigned] video_vbase drivers/staging/xgifb/XGI_main_26.c:2430:31: warning: incorrect type in argument 1 (different address spaces) drivers/staging/xgifb/XGI_main_26.c:2430:31: expected void volatile [noderef] <asn:2>*addr drivers/staging/xgifb/XGI_main_26.c:2430:31: got char *[addressable] [toplevel] [assigned] video_vbase drivers/staging/xgifb/XGI_main_26.c:2454:31: warning: incorrect type in argument 1 (different address spaces) drivers/staging/xgifb/XGI_main_26.c:2454:31: expected void volatile [noderef] <asn:2>*addr drivers/staging/xgifb/XGI_main_26.c:2454:31: got char *[addressable] [toplev Signed-off-by: Aaro Koskinen <aaro.koskinen@iki.fi> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
