This is a note to let you know that I've just added the patch titled soc/tegra: fuse: Drop Kconfig dependency on TEGRA20_APB_DMA to the 5.15-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: soc-tegra-fuse-drop-kconfig-dependency-on-tegra20_ap.patch and it can be found in the queue-5.15 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit fa91eb5ebf198d2af4fba1827fc9b625df94a8e4 Author: Dmitry Osipenko <digetx@xxxxxxxxx> Date: Wed Sep 23 03:34:21 2020 +0300 soc/tegra: fuse: Drop Kconfig dependency on TEGRA20_APB_DMA [ 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.
