From 20cef813b4791ba55b2f3c4258414b6ded21e8ff Mon Sep 17 00:00:00 2001 From: David Herrmann Date: Sun, 5 May 2013 23:12:52 +0200 Subject: HID: wiimote: convert KEYS and RUMBLE to modules This introduces the first sub-device modules by converting the KEYS and RUMBLE sub-devices into wiimote modules. Both must be converted at once because they depend on the built-in shared input device. This mostly moves code from wiimote-core to wiimote-modules and doesn't change any semantics or ABI.
