You seem to have sent me many different series of patches for this
driver, some of them the same, some different, some duplicates.  I have
no idea what to apply and what not to apply, so I'm dropping them all
from my patch queue.  Please fix up and resend a _single_ patch series
with your patches so I know what to review and possibly apply.

thanks,

It's not in my queue at all, all speakup patches are now flushed out, so
if I have not applied it, please resend.
