[ Upstream commit 2254182807fc09ba9dec9a42ef239e373796f1b2 ]
The DMA subsystem could be entirely disabled in Kconfig and then the
TEGRA20_APB_DMA option isn't available too. Hence kernel configuration
fails if DMADEVICES Kconfig option is disabled due to the unsatisfiable
dependency.
The FUSE driver isn't a critical driver and currently it only provides
NVMEM interface to userspace which isn't known to be widely used, and
thus, it's fine if FUSE driver fails to load.
Let's remove the erroneous Kconfig dependency and let the FUSE driver to
fail the probing if DMA is unavailable.
Fixes: 19d41e5e9c ("soc/tegra: fuse: Add APB DMA dependency for Tegra20")

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.
