[PATCH 01/11] i2c: at91: Use devm_platform_get_and_ioremap_resource()

[Yangtao Li]

Convert platform_get_resource(), devm_ioremap_resource() to a single
call to devm_platform_get_and_ioremap_resource(), as this is exactly
what this function does.

"pdev" does not exist in this context.
Please try to at least compile-test your patches before submitting them.

While at it, you could get rid of "res", and replace it by "pd->res" in the
above call to devm_platform_get_and_ioremap_resource().
