-commit 4fe4f9fecc36956fd53c8edf96dd0c691ef98ff9 upstream.
-
-Disabling all EP's allow to reset EP's to initial state.
-Introduced new function dwc2_hsotg_ep_disable_lock() which
-before calling dwc2_hsotg_ep_disable() function acquire
-hsotg->lock and release on exiting.
-From dwc2_hsotg_ep_disable() function removed acquiring
-hsotg->lock.
-In dwc2_hsotg_core_init_disconnected() function when USB
-reset interrupt asserted disabling all ep’s by
-dwc2_hsotg_ep_disable() function.
-This updates eliminating sparse imbalance warnings.
-
-Reverted changes in dwc2_hostg_disconnect() function.
-Introduced new function dwc2_hsotg_ep_disable_lock().
-Changed dwc2_hsotg_ep_ops. Now disable point to
-dwc2_hsotg_ep_disable_lock() function.
-In functions dwc2_hsotg_udc_stop() and dwc2_hsotg_suspend()
-dwc2_hsotg_ep_disable() function replaced by
-dwc2_hsotg_ep_disable_lock() function.
-In dwc2_hsotg_ep_disable() function removed acquiring
-of hsotg->lock.
