Hi All, Before I send another version of this patch I have one question: I am seeing /warnings from arch/riscv/include/asm/io.h In my Kconfig I have: depends on SOC_MT7621 || COMPILE_TEST I need to keep the include/linux/dma-mapping.h so should I remove the COMPILE_TEST or can I safely ignore those warnings?
