Hi Jiri,
Here are four patches intended for the 3.19 stream and are based on jikos/hid (for-next, v3.18-rc4-144-gd9372ee).
* The first is actually from Benjamin Tissoires, but modified to remove a now unneeded goto. * The second one depends on the first (it could work without, but there will be a context mismatch). * The third one can be applied independently of the others and is needed to avoid a possible buffer overread. * The fourth and final patch fixes an unbalanced hid_device_io_start().
Tested by booting with three paired USB devices (QEMU + USB passthrough), two of them are powered off and one M525 is active. evbug registers mouse events.
Kind regards, Peter
