Currently, force_pio is cleared when the driver exits. Then, it resulted in clearing it in multiple places since MMC drivers in general have multiple exit points. tmio_mmc_reset_work - bails out on timeout tmio_process_mrq - error out when it cannot send a command tmio_mmc_finish_request - successful exit This is error-prone since we may miss to cover all bail-out points. To simplify the code, the data structure should be initialized just before used since we have a single entrance. force_pio is only used for data transfer, so tmio_mmc_start_data() will be a suitable place to clear this flag.

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.
