Some uas patches for the Fedora kernel

[Hans de Goede]

Hi Josh,

Attached are 3 patches for the current F-21 kernel,
fixing various uas issues. All 3 have been
sent upstream.

The first 2 patches fix issues reported through various
channels (mostly direct emails to me), the third one
fixes:

https://bugzilla.redhat.com/show_bug.cgi?id=1124119

Can you please add these to the Fedora kernel builds?

Regards,

Hans
