Pull devm usage cleanup from Wolfram Sang: "Lately, I have been experimenting how to improve the devm interface to make writing device drivers easier and less error prone while also getting rid of its subtle issues. I think it has more potential but still needs work and definately conistency, especiall in its usage. The first thing I come up with is a low hanging fruit regarding devm_ioremap_resouce(). This function already checks if the passed resource is valid and gives an error message if not. So, we can remove similar checks from the drivers and get rid of a bit of code and a number of inconsistent error strings. This series only removes the unneeded check iff devm_ioremap_resource follows platform_get_resource directly. The previous version tried to shuffle code if needed, too, what lead to an embarrasing bug. It turned out to me that shuffling code for all cases found will make the automated script too complex, so I am unsure if an automated cleanup is the proper tool for this case. Removing the easy stuff seems worthwhile to me, though. Despite various architectures and platform dependencies, I managed to compile test 45 out of 57 modified files locally using heuristics and defconfigs."
