From f3fb802efaef3662744a2215a51294d52a7cfc0e Mon Sep 17 00:00:00 2001 From: Roger Quadros Date: Wed, 23 Oct 2019 12:02:32 +0300 Subject: [PATCH] usb: cdns3: gadget: Don't manage pullups The USB gadget core is supposed to manage pullups of the controller. Don't manage pullups from within the controller driver. Otherwise, function drivers are not able to keep the controller disconnected from the bus till they are ready.
