You are describing what your patch is doing, but fail to provide any explanation why this patch is required and which problem it actucally solves. See: https://www.kernel.org/doc/html/latest/process/maintainer-tip.html#changelog When you read that document, please read the paragraph about selecting the subsystem prefix too. Thanks, tglx
