The 24HD has 1 button per LED (first three buttons of each group).
We need a special treatment for them as it's not a uniq button that
switches between the LEDs.

The code for 21UX2 and 24HD makes the LED group 1 on the left, and
the group 0 on the right. The buttons are ordered in the other way,
but libwacom already exports those that way. So we simply can't reassign
LED group 0 to the left buttons, and have to quirk the incoming data...

The EKR switches the LED directly, and there is no point in having
userspace handling the switch it self when it's easy enough to do
in the kernel.
The other benefit is that now userspace does not need to have root access
to the LED but need only to read them with user privileges.

There is a bug (?) in devm_led_classdev_register() in which its increments
the refcount of the parent. If the parent is an input device, that means
the ref count never reaches 0 when devm_input_device_release() gets called.
This means that the LEDs and all the devres resources attached to the
input device are not released.
Manually force the release of the group so that the leds are released once
we are done using them.

Previously, all the remotes attached to the same receiver would share the

Thanks to devres, we can now afford to create more than one input node
without having to overload the remove/failure paths. Having one input
node per remote is something which should have been implemented from start
but the probability of having users with several remotes is quite low.
Anyway, still, better looking at the future and implement things properly.
Remote input nodes will be freed/unregistered magically as they are
created in the devres group &remote->remotes[index].
We need to open the hid node now that the remotes are dynamically
allocated.

Add i2c_hid_shutdown for i2c-hid driver to send suspend cmd & free

Some HW design (i.e. Umaro, a chromebook model) is that the power to
i2c hid device won't down after device shutdown. Also the i2c-hid driver
do not send suspend cmd to the hid i2c device and free its irq before
shutdown.So if We touch the touchscreen or some other i2c hid device,
the power consumtion will be go up even when the device is in shutdown
state.
