Hi Clément, your commit dece45855a8b ("NFC: nxp-nci: Add support for NXP NCI chips") adds the Makefile drivers/nfc/nxp-nci/Makefile with the following line: +ccflags-$(CONFIG_NFC_DEBUG) := -DDEBUG The Kconfig option NFC_DEBUG is not defined so the line turns out to be a nop. There is another reference in drivers/nfc/Makefile. Is there a patch queued somewhere to add the option? I found this issue with ./scripts/checkkconfigsymbols.py by diffing v4.0 and v4.1-rc1.
