Alex Elder says:

====================
net: ipa: prevent shutdown during setup

The setup phase of the IPA driver occurs in one of two ways.
Normally, it is done directly by the main driver probe function.
But some systems (those having a "modem-init" DTS property) don't
start setup until an SMP2P interrupt (sent by the modem) arrives.

Because it isn't performed by the probe function, setup on
"modem-init" systems could be underway at the time a driver
remove (or shutdown) request arrives (or vice-versa).  This
situation can lead to hardware state not being cleaned up
properly.

This series addresses this problem by having the driver remove
function disable the setup interrupt.  A consequence of this is
that setup will complete if it is underway when the remove function
is called.

So now, when removing the driver, setup:
  - will have already completed;
  - is underway, and will complete before proceeding; or
  - will not have begun (and will not occur).

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.
