From 21acc656a06e912341d9db66c67b58cc7ed071e7 Mon Sep 17 00:00:00 2001 From: Paul Cercueil Date: Wed, 26 Oct 2022 19:26:51 +0100 Subject: usb: musb: Add and use inline functions musb_{get,set}_state Instead of manipulating musb->xceiv->otg->state directly, use the newly introduced musb_get_state() and musb_set_state() inline functions. Later, these inline functions will be modified to get rid of the musb->xceiv dependency, which prevents the musb code from using the generic PHY subsystem.
