Subject: [PATCH 0/3] HID: logitech-{dj,hidpp}: more reliability fixes

Hi Jiri,

Here are more fixes intended for the 3.19 tree after a review. Two bugfixes.
one which was mentioned in a mail with Benjamin ("avoid unintended
fall-through") and a fix to avoid a possible 5 second delay for HID++ 2.0
errors. I haven't encountered a case where the hidpp module generates a HID++
2.0 error though, so maybe that change can go to 3.20 too if you want to keep
the changeset small.

The third (second) patch adds a check to avoid passing a short report. A similar
fix should probably be written for stable kernels (the code was changed in 3.19,
but the length check was already missing in older kernels).

Kind regards,
Peter
