unregister after reset is clearly wrong - device can be used while it's reset. There's an attempt to protect against that using hwrng_removed but it seems racy since access can be in progress when the flag is set. Just unregister, then reset seems simpler and cleaner. NB: we might be able to drop hwrng_removed in a follow-up patch. Signed-off-by: Laurent Vivier <lvivier@redhat.com> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
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.
