Mario Limonciello 1a760d10de thunderbolt: Fix a logic error in wake on connect 
commit a5cfc9d658 ("thunderbolt: Add wake on connect/disconnect
on USB4 ports") introduced a sysfs file to control wake up policy
for a given USB4 port that defaulted to disabled.

However when testing commit 4bfeea6ec1 ("thunderbolt: Use wake
on connect and disconnect over suspend") I found that it was working
even without making changes to the power/wakeup file (which defaults
to disabled). This is because of a logic error doing a bitwise or
of the wake-on-connect flag with device_may_wakeup() which should
have been a logical AND.

Adjust the logic so that policy is only applied when wakeup is
actually enabled.

Fixes: a5cfc9d658 ("thunderbolt: Add wake on connect/disconnect on USB4 ports")

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 reStructuredText 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.
