Fix compilation errors introduced during the snapshot from msm-4.14 and subsequent cherry-picks. - Add missing linux/usb/usbpd.h header - Upstream moved extcon definitions to <linux/extcon-provider.h> - Fix missing space after '=' in Makefile, otherwise 'pd' subdirectory fails to be included - Fix a few places where break/return were incorrectly used - MSG_BATTERY_STATUS is not an extended message so handling should have been done in handle_data_snk_ready() Change-Id: I248b17a8479572b53b2a792877460d6474bca113 Signed-off-by: Jack Pham <jackp@codeaurora.org>
