I suggest to improve also this change description. * Should the mentioned identifiers refer to variables? * Will another imperative wording be preferred? https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/process/submitting-patches.rst?id=b791d1bdf9212d944d749a5c7ff6febdba241771#n151 * I propose to extend the patch a bit more. How do you think about to convert the initialisation for the variable “ret” also into a later assignment? Regards, Markus
