When SDHC gets reset (E.g. in runtime suspend path), CQE also gets reset and goes to disable state. But s/w state still points it as CQE is in enabled state. Since s/w and h/w states goes out of sync, it results in s/w request timeout for subsequent CQE requests. To synchronize CQE s/w and h/w state during SDHC reset, explicitly deactivate CQE just before SDHC reset.

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.
