Ben Hutchings 4ffad598bf scsi: dpt_i2o: Do not process completions with invalid addresses
adpt_isr() reads reply addresses from a hardware register, which
should always be within the DMA address range of the device's pool of
reply address buffers.  In case the address is out of range, it tries
to muddle on, converting to a virtual address using bus_to_virt().

bus_to_virt() does not take DMA addresses, and it doesn't make sense
to try to handle the completion in this case.  Ignore it and continue
looping to service the interrupt.  If a completion has been lost then
the SCSI core should eventually time-out and trigger a reset.

There is no corresponding upstream commit, because this driver was
removed upstream.

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.
