From 8879904b1935a1eafa688eb0d86aff0fa7907afb Mon Sep 17 00:00:00 2001 From: Johan Hovold Date: Wed, 19 May 2021 11:33:02 +0200 Subject: [PATCH] USB: dwc2: drop irq-flags initialisations There's no need to initialise irq-flags variables before saving the interrupt state. While at it drop two redundant return-value initialisations from two of the functions that got it wrong.
