The change looks good, it's definitely a step in the right direction. Acked-by: Arnd Bergmann <[email protected]> I think you can go even further: * A straightforward change would be to move davinci_sysmodbase into a local variable of the davinci_setup_mmc function, which I believe is the only user. Then you can ioremap and iounmap it directly there. * If you need to access sysmod in multiple places, a nicer way would be to make the virtual address pointer static, and export the accessor functions for it, rather than having a global pointer.
