From 31927b6b68acd21258b1f4ef24464acae60cfd36 Mon Sep 17 00:00:00 2001 From: Gregory Herrero Date: Tue, 22 Sep 2015 15:16:41 +0200 Subject: [PATCH] usb: dwc2: host: update hcd and lx_state during start/stop callbacks During hcd initialization, hardware accessible flag and lx_state must be reset to the working state since controller is powered at this stage. Same logic applied for stop callback.
