You are right that this function implementation does a bit more before returning because of a detected null pointer. https://git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git/tree/net/xfrm/xfrm_ipcomp.c?id=394efd19d5fcae936261bd48e5b33b21897aacf8#n247 Can you agree that input parameter validation is also performed there? Do you want that I resend my patch with a corrected commit message?
