Please stop and take a break for a day.

Look at the subject line of your email, is that what the other subject
lines for this mailing list look like?  You can see all of the prior
emails on the list on lore.kernel.org if you want some examples.

Ok, but this does not match your signed-off-by line, as my bot told you
to fix, why not?

That is a very long subject line, your editor told you to only use 50 or
so characters, please follow that rule.

Why is this even here at all?  We don't track CVE numbers for kernel
patches, that's crazy and insane and even MITRE agrees that CVEs do not
make any sense at all for the Linux kernel.  So don't even attempt to
classify something as "no CVE here" as that makes no sense.

That seems very odd, what about the USB 3 connection for this device?
Why is UAS so slow for this specific device?

Why all versions?  Why not just your one specific one?

Also, your patch is corrupted and can not be applied at all :(

Please take a day off, relax, and come back in a few days and resubmit a
fixed up commit after reading our documentation for how to properly
write and submit a kernel change.

thanks,
