commita0741ba40aupstream. During a re-initialization of the eMMC card, we may fail to re-enable HPI. In these cases, that isn't properly reflected in the card->ext_csd.hpi_en bit, as it keeps being set. This may cause following attempts to use HPI, even if's not enabled. Let's fix this!

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.
