ASoC: Intel: kbl_rt5663_max98927: Map BTN_0 to KEY_PLAYPAUSE
The Android 3.5mm Headset jack specification mentions that BTN_0 should be mapped to KEY_MEDIA, but this is less logical than KEY_PLAYPAUSE, which has much broader userspace support. For example, the Chrome OS userspace now supports KEY_PLAYPAUSE to toggle play/pause of videos and audio, but does not handle KEY_MEDIA. Furthermore, Android itself now supports KEY_PLAYPAUSE equivalently, as the new USB headset spec requires KEY_PLAYPAUSE for BTN_0. https://source.android.com/devices/accessories/headset/usb-headset-spec Signed-off-by: Benson Leung <bleung@chromium.org> Signed-off-by: Mark Brown <broonie@kernel.org>
