Wenchao Chen 1796ae6a7a mmc: sdhci-sprd: Fix vqmmc not shutting down after the card was pulled
[ Upstream commit 477865af60b2117ceaa1d558e03559108c15c78c ]

With cat regulator_summary, we found that vqmmc was not shutting
down after the card was pulled.

cat /sys/kernel/debug/regulator/regulator_summary

README

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

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.
