As these are mostly one-liners and straight forward changes, posting during RC is not an option for 5.12 inclusion? Regards, -Arun

This doesn't seem like either, but please clarify if it is. From the commit log, it looks like this is just a cleanup with no benefit to the user. If that's the case, there's no reason to backport to stable either. Bjorn

My bad in not stating that well in the commit log. In retrospect, this was mentioned only in a prior e-mail (link[2] above -- sorry about our exchange servers mangling the URL and redirecting it via proofpoint). I can re-send the patch to correctly reflect it as a fix. Something like: Subject: "PCI/VPD: Fix blocking of VPD data in lspci for QLogic 1077:2261" What do you think? Regards, -Arun

Something like: > > Subject: "PCI/VPD: Fix blocking of VPD data in lspci for QLogic 1077:2261" Yes, that would be useful :) The commit log needs to explain why the patch should be merged. Bjorn
