Hi All, Here is a patch series adding support for the extra keys and LEDs on Logitech G15, G15 v2 and G510 keyboards, as well as adding support for controlling the keyboard backlight on these models. This v2 is mostly a resend, the only change is the addition of a missing mutex_init() call in the 3th patch in the series. Dmitry, the first patch adds a bunch of new key-codes for these and other similar keyboards to input-event-codes.h, the other patches depend on this. It is probably best if this patch is merged through the HID tree as part of the rest of the series. If that is ok with you, can we please have your ack for this? Regards, Hans
