Thanks for the analysis and the bug fix!
I asked Tom Zanussi and he kindly reviewed your patch and provided an
Acked-by tag for it, Tom, may I add a Reviewed-by: as well?
Joseph, can I have your Signed-off-by: tag, as documented in:
Documentation/SubmittingPatches
In the "12) Sign your work" section?
Thanks!
