This is a note to let you know that I've just added the patch titled drm/sun4i: fix unmet dependency on RESET_CONTROLLER for PHY_SUN6I_MIPI_DPHY 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: drm-sun4i-fix-unmet-dependency-on-reset_controller-f.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 047207c42cca68fe5813ed5da8a1219e1ee33972 Author: Julian Braha <julianbraha@xxxxxxxxx> Date: Mon Nov 8 22:23:51 2021 -0500 drm/sun4i: fix unmet dependency on RESET_CONTROLLER for PHY_SUN6I_MIPI_DPHY [ Upstream commit bb162bb2b4394108c8f055d1b115735331205e28 ] When PHY_SUN6I_MIPI_DPHY is selected, and RESET_CONTROLLER is not selected, Kbuild gives the following warning: WARNING: unmet direct dependencies detected for PHY_SUN6I_MIPI_DPHY Depends on [n]: (ARCH_SUNXI [=n] || COMPILE_TEST [=y]) && HAS_IOMEM [=y] && COMMON_CLK [=y] && RESET_CONTROLLER [=n] Selected by [y]: - DRM_SUN6I_DSI [=y] && HAS_IOMEM [=y] && DRM_SUN4I [=y] This is because DRM_SUN6I_DSI selects PHY_SUN6I_MIPI_DPHY without selecting or depending on RESET_CONTROLLER, despite PHY_SUN6I_MIPI_DPHY depending on RESET_CONTROLLER. These unmet dependency bugs were detected by Kismet, a static analysis tool for Kconfig. Please advise if this is not the appropriate solution. v2: Fixed indentation to match the rest of the file.
