[media] media: davinci: vpbe: fix build warning
Warnings were generated because of the following commit changed data type for address pointer 195bbca ARM: 7500/1: io: avoid writeback addressing modes for __raw_ accessors add __iomem annotation to fix following warnings 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’ This patch stores the ioremap_nocache() returned address in a void __iomem * instead of a unsigned long and passes the same to readl/writel functions which fixes the above warnings.
