Jamie Iles ff0e4d4c97 mailbox: pcc: don't zero error register
The error status mask for a type 3/4 subspace is used for reading the
error status, and the bitwise inverse is used for clearing the error
with the intent being to preserve any of the non-error bits.  However,
we were previously applying the mask to extract the status and then
applying the inverse to the result which ended up clearing all bits.

Instead, store the inverse mask in the preserve mask and then use that
on the original value read from the error status so that only the error
is cleared.

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 reStructuredText 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.
