Dear Pavel,

I like the code, just a few things though:
(1) the comments I made in the previous e-mail r.e. what we actually
do with the errors, and grouping logically related changes (the rest
of the usb_read*() changes being in this patch for example).
(2) I got trailing whitespace errors from this patch and the last one.
For a v2 I would say stripping the whitespace is a good idea too - I
have submitted many patches myself to this driver that had whitespace
in - indeed, the original version of my patch series to import the
driver still had a load as well :-)

Regards,
Phil
