[ Upstream commit 4bf780996669280171c9cd58196512849b93434e ] Existing data command CRC error handling is non-standard and does not work with some Intel host controllers. Specifically, the assumption that the host controller will continue operating normally after the error interrupt, is not valid. Change the driver to handle the error in the same manner as a data CRC error, taking care to ensure that the data line reset is done for single or multi-block transfers, and it is done before unmapping DMA.

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.
