Dear Mauro Thanks for your review. We will refer to your comments and consider how to respond for them. I want to confirm one thing about SPDX license text We will add SPDX license text to our files, Is it necessary to add SPDX not only .c .h Makefile but also Kconfig? When I checked current files in driver/media, there is no Kconfig file which has SPDX. Best Regards, Takiguchi
