Dear Greg, The script ./scripts/checkkconfigsymbols.py warns on invalid references to Kconfig symbols (often, minor typos, name confusions or outdated references). This patch series addresses all issues reported by ./scripts/checkkconfigsymbols.py in ./drivers/usb/ for Kconfig and Makefile files. Issues in the Kconfig and Makefile files indicate some shortcomings in the overall build definitions, and often are true actionable issues to address. These issues can be identified and filtered by: ./scripts/checkkconfigsymbols.py | grep -E "drivers/usb/.*(Kconfig|Makefile)" -B 1 -A 1 After applying this patch series on linux-next (next-20210816), the command above yields just one further issues to address: ARCH_VERSAL Referencing files: drivers/usb/dwc3/Kconfig For this remaining issue, I already contacted Manish Narani, the contributor of ./drivers/usb/dwc3/, to clarify the intent of that config dependency. Please pick this patch series into your usb-next tree.
