It is recommended to use managed function devm_ioremap_resource(), which simplifies driver cleanup paths and driver code. This patch does the following: (a) replace request_mem_region(), ioremap() and corresponding error handling with devm_ioremap_resource(). (b) remove struct resource pointer(res_mem) in struct ssi_drvdata as it seems redundant, use struct resource pointer which is defined locally and adjust return value of platform_get_resource() accordingly. (c) release_mem_region() and iounmap() are dropped, since devm_ioremap_ resource() releases and unmaps mem region on driver detach. (d) adjust log messages accordingly and remove any blank lines.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
