Uwe Kleine-König 3d82475ad4 net: dsa: mv88e6xxx: fix races between lock and irq freeing
free_irq() waits until all handlers for this IRQ have completed. As the
relevant handler (mv88e6xxx_g1_irq_thread_fn()) takes the chip's reg_lock
it might never return if the thread calling free_irq() holds this lock.

For the same reason kthread_cancel_delayed_work_sync() in the polling case
must not hold this lock.

Also first free the irq (or stop the worker respectively) such that
mv88e6xxx_g1_irq_thread_work() isn't called any more before the irq
mappings are dropped in mv88e6xxx_g1_irq_free_common() to prevent the
worker thread to call handle_nested_irq(0) which results in a NULL-pointer
exception.

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.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
