commit ce385dd8221b35541533241cc6134d4b99694b56 Author: Furquan Shaikh furquan@chromium.org Date: Mon Feb 13 13:22:19 2017 -0800
device: Add scan_generic_bus support
scan_smbus routine does not perform any smbus specific operation. Thus, rename the routine to scan_generic_bus so that it can be used by other buses like SPI. Add a wrapper scan_smbus to allow other users of smbus scan to continue working as before.
