commit 7994db905c0fd692cf04c527585f08a91b560144 upstream.
The __init annotation makes the ks_pcie_probe() function disappear after
booting completes. However a device can also be bound later. In that case,
we try to call ks_pcie_probe(), but the backing memory is likely already
overwritten.
The right thing to do is do always have the probe callback available. Note
that the (wrong) __refdata annotation prevented this issue to be noticed by
modpost.

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.
