Sean RhodesandGreg Kroah-Hartman 41822c1dfd drivers/card_reader/rtsx_usb: Restore interrupt based detection
commit 235b630eda upstream.

This commit reintroduces interrupt-based card detection previously
used in the rts5139 driver. This functionality was removed in commit
00d8521dcd ("staging: remove rts5139 driver code").

Reintroducing this mechanism fixes presence detection for certain card
readers, which with the current driver, will taken approximately 20
seconds to enter S3 as `mmc_rescan` has to be frozen.

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.
