The fix is in patch 3/3, but requires a separate fixes in patches 1/3 and 2/3 to avoid circular dependencies: drivers/i2c/Kconfig:8:error: recursive dependency detected! drivers/i2c/Kconfig:8: symbol I2C is selected by FB_DDC drivers/video/fbdev/Kconfig:63: symbol FB_DDC depends on FB drivers/video/fbdev/Kconfig:12: symbol FB is selected by DRM_KMS_FB_HELPER drivers/gpu/drm/Kconfig:80: symbol DRM_KMS_FB_HELPER depends on DRM_KMS_HELPER drivers/gpu/drm/Kconfig:74: symbol DRM_KMS_HELPER is selected by DRM_ZYNQMP_DPSUB drivers/gpu/drm/xlnx/Kconfig:1: symbol DRM_ZYNQMP_DPSUB depends on DMA_ENGINE drivers/dma/Kconfig:44: symbol DMA_ENGINE depends on DMADEVICES drivers/dma/Kconfig:6: symbol DMADEVICES is selected by SND_SOC_SH4_SIU sound/soc/sh/Kconfig:30: symbol SND_SOC_SH4_SIU is selected by SND_SIU_MIGOR sound/soc/sh/Kconfig:60: symbol SND_SIU_MIGOR depends on I2C For a resolution refer to Documentation/kbuild/kconfig-language.rst subsection "Kconfig recursive dependency limitations" Due to the DPSUB driver being merged in v5.9, this is a candidate fix for v5.9 as well. 1/3 and 2/3 can be merged independently, 3/3 depends on the first two. What's the best course of action, can I merge this all in a single tree, or should the rapidio and ASoC patches be merged independently early in the -rc cycle, and the DRM patch later on top ? I don't expect conflicts (especially in 2/3 and 3/3), so merging the whole series in one go would be simpler in my opinion. Compared to v1, commit messages have been fixed to mention DMADEVICES instead of DMAENGINES.
