commit 08df2d7dd4ab2db8a172d824cda7872d5eca460a upstream.
rc is overwritten by the evtchn_status hypercall in each iteration, so
the return value will be whatever the last iteration is. This could
incorrectly return success even if the event channel was not found.
Change to an explicit -ENOENT for an un-found virq and return 0 on a
successful match.
Fixes: 62cc5fc7b2 ("xen/pv-on-hvm kexec: rebind virqs to existing eventchannel 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 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.
