drivers/media/platform/davinci/vpbe_osd.c: In function ‘osd_read’:
drivers/media/platform/davinci/vpbe_osd.c:49:2: warning: passing
 argument 1 of ‘__raw_readl’ makes pointer from integer without a cast [enabled by default]
arch/arm/include/asm/io.h:104:19: note: expected ‘const volatile
 void *’ but argument is of type ‘long unsigned int’
