From 986bd947bcd1f5bace488a739218bfc3ca407de8 Mon Sep 17 00:00:00 2001 From: Johan Hovold Date: Tue, 4 Apr 2023 09:25:15 +0200 Subject: [PATCH] USB: dwc3: fix runtime pm imbalance on unbind commit 44d257e9012ee8040e41d224d0e5bfb5ef5427ea upstream. Make sure to balance the runtime PM usage count on driver unbind by adding back the pm_runtime_allow() call that had been erroneously removed.
