9a2e1571c0 rules: avoid 'device/' accesses
We should never access parents, as the sysfs hierarchy is in no way
stable. Use KERNELS== etc. to match on a parent, then access it via
$attr{} (which accesses the matching device, not the current device).

568d800b78 rules: fix input-name for keyboard rules
We match on the evdev node, but only the parent has a "name" attribute.
Use $attr{device/name} to access it.

This is borked since 2013, I wonder how that ever worked? Maybe this will
suddenly fix all the DMI-based key detections.

Thanks to Peter Hutterer for catching this!

b17de8449c Revert "hwdb: merge atkbd into platform matches"
This reverts commit ba76ee29bc. As it turns
out, we need to match on driver=atkbd to not load the fixups on any
plugged USB devices.

That is, whenever you use "name:<name>:dmi:<dmi>" style matches, you
better provide a name or you're screwing things up.

ba76ee29bc hwdb: merge atkbd into platform matches
Currently, we always run
  hwdb 'keyboard:name:$attr{name}:$attr{[dmi/id]modalias}'
as last step to match keyboards. Therefore, if nothing else matched so
far, we still try the device-name+dmi combination.

However, we have a special atkbd rule which is only run for atkbd as:
  hwdb 'keyboard:$attr{[dmi/id]modalias}'

This is redundant, as we already pass the same information to hwdb in the
last fallback step.

This patch converts the hwdb "keyboard:dmi:*" matches to
"keyboard:name:*:dmi:*" matches and drops the redundant rule.

a9c30bca57 rules: drop redundant match
The 60-keyboard rules are already guared by KERNEL!="event*" bail-outs,
therefore, KERNELS="input*" is always true. Drop it!

aee26b1276 hwdb: support bluetooth keyboard fixups
Drop the restriction not to match on bluetooth devices. They are supported
just fine!

b26e4ced91 hwdb: convert to generic input-modalias matches
There is no reason to match on usb-modaliases, if we can use the
input-modalias to achieve the same. This commit changes the
keyboard-lookups to not be restricted to USB, but pass all modaliases to
the hwdb. Furthermore, we convert all usb:* matches to input:* matches,
thus getting rid of any ambiguity if multiple usb devices are chained (or
a bluetooth device / etc. is on top).

Note that legacy keyboard:usb:* matches are still supported, but
deprecated. If possible, please use keyboard:input:* matches instead.

This is a required step to make other input devices work with
60-keyboard.hwdb. Other bus-types are often chained on usb and we want to
avoid any ambiguity here if we incorrectly match on a USB hub.

49804365ea udev: keyboard - also hook into "change" events
Re-apply the keymaps when "udevadm trigger" is called. Hooking into
"add" only would just remove all keymap content from the udev database
instead of applying the new config.
