Any reason we can't just remove it ? No ... idea. Looks like it was added in: commit b41e5fffe8b81fc939067d8c1c195cc79115d5a3 Author: Emil Medve AuthorDate: Sat May 3 06:34:04 2008 +1000 Commit: Paul Mackerras CommitDate: Mon May 5 16:47:14 2008 +1000 [POWERPC] devres: Add devm_ioremap_prot() We provide an ioremap_flags, so this provides a corresponding devm_ioremap_prot. The slight name difference is at Ben Herrenschmidt's request as he plans on changing ioremap_flags to ioremap_prot in the future.
