From 8d736d8a9c44547f14711c52875c88d19d8b287b Mon Sep 17 00:00:00 2001 From: Dinh Nguyen Date: Tue, 11 Nov 2014 11:13:38 -0600 Subject: [PATCH] usb: dwc2: gadget: Do not fail probe if there isn't a clock node Since the dwc2 hcd driver is currently not looking for a clock node during init, we should not completely fail if there isn't a clock provided. By assigning clk = NULL, this allows the driver, when configured for dual-role mode, to be able to continue loading the host portion of the driver when a clock node is not specified.
