Just to check my understanding here - does this change mean that the keys marked as KEY_RESERVED in the lenovo map won't make it into the mask?
e.g the ones in this block:
KEY_RESERVED, /* Mute held, 0x103 */
KEY_BRIGHTNESS_MIN, /* Backlight off */
KEY_RESERVED, /* Clipping tool */
KEY_RESERVED, /* Cloud */
KEY_RESERVED,
KEY_VOICECOMMAND, /* Voice */
KEY_RESERVED,
KEY_RESERVED, /* Gestures */
KEY_RESERVED,
KEY_RESERVED,
KEY_RESERVED,
KEY_CONFIG, /* Settings */
KEY_RESERVED, /* New tab */
KEY_REFRESH, /* Reload */
KEY_BACK, /* Back */
KEY_RESERVED, /* Microphone down */
KEY_RESERVED, /* Microphone up */
KEY_RESERVED, /* Microphone cancellation */
KEY_RESERVED, /* Camera mode */
KEY_RESERVED, /* Rotate display, 0x116 */
I'm not sure what the effect will be and I don't have the 2014 X1 Carbon (I assume it's the G1) available to test with unfortunately.
Just wanted to be sure we weren't breaking something on older platforms.
