sdhci uses CONFIG_MMC_DEBUG for showing ADMA descriptor when occurring ADMA error. And it's also used to dump the registers whenever calling sdhci_add_host. On one hand, I don't see any burden to always print the state ADMA descriptor as it's rare and will help folks better understand what was happening when seeing ADMA error. On the other, folks may be interested in checking some registers at probe time. So we remove the sdhci_dumpregs from __sdhci_add_host and print some really useful registers in sdhci_setup_host.

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.
