--------------------------------
[ 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.
