Dan Carpenter f013a5001b usb: gadget: r8a66597: fix a loop in set_feature()
commit 17956b53ebff6a490baf580a836cbd3eae94892b upstream.

This loop is supposed to loop until if reads something other than
CS_IDST or until it times out after 30,000 attempts.  But because of
the || vs && bug, it will never time out and instead it will loop a
minimum of 30,000 times.

This bug is quite old but the code is only used in USB_DEVICE_TEST_MODE
so it probably doesn't affect regular usage.

Fixes: 96fe53ef54 ("usb: gadget: r8a66597-udc: add support for TEST_MODE")

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.
