Hi Ghanshyam,

Thank you for the patch, but it is sadly incorrect.

You have created this V2 against a tree including the V1 version of your
patch. A V2 patch should apply cleanly against the source tree, with no
previous version first needing to be applied.

On another note, why are you using dev_warn_ratelimited here, and if
there's a good reason, why not use it for the other callsites in this
function? (Genuine question here, I've not studied the difference).

Please create a V3, many thanks.
