[ Upstream commit 8e0e7bd38b1ec7f9e5d18725ad41828be4e09859 ]
If sdhci-omap is configured for an unused device instance and the device
is not set as disabled, we can get a NULL pointer dereference:
Unable to handle kernel NULL pointer dereference at virtual address
00000045

AFAIK we are not seeing this with the devices configured in the mainline
kernel but this can cause issues for folks bringing up their boards.
Fixes:

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.
