The types added for input in InputClassifier HAL are not specific to that HAL. These are common input definitions. To allow for future reuse in this and other HALs, move these definitions into a separate, type-only HAL android::hardware::input::common. This will be similar to such existing HALs as: hardware/interfaces/graphics/common hardware/interfaces/camera/common hardware/interfaces/audio/common Test: make only Bug: 111480215 Change-Id: I16d76d6bdb48b24487b232fda45c6146e1003fe9
