Mika Kuoppala 8455dad7ba drm/i915/icl: Don't warn on spurious interrupts
There is a chance we can see spurious interrupts in live
now. We have more engines enabled and that with more elaborate
access patterns with pm and display, increases the chances
hardware just makes a social call, without anything to work on.

Remove the error as we have tests to actually probe if
we really miss interrupt, instead of getting spurious ones.

Note that now we do write to intr_dw even with a zero
value. This is considered advantegous as the write
is an ack that sw is done.

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.
