Pinephone running on Allwinner A64 fails to suspend with USB devices connected as reported by Bhushan Shah <bshah@kde.org>. Reverting commit 5fbf7a253470 ("usb: musb: fix idling for suspend after disconnect interrupt") fixes the issue.

This is also needed on am335x to suspend with devices connected in addition to a64 --- drivers/usb/musb/musb_core.c | 12 ++++++++---- 1 file changed, 8 insertions(+), 4 deletions(-)
