When the dr_mode is "host", after the host enter runtime suspend, the mtu3 can't do it, because the mtu3's device wakeup function is not enabled, instead it's enabled in gadget init function, to fix the issue, init wakeup early in mtu3's probe() Fixes: 6b587394c65c ("usb: mtu3: support suspend/resume for dual-role mode") Reported-by: Tianping Fang <tianping.fang@mediatek.com> Signed-off-by: Chunfeng Yun <chunfeng.yun@mediatek.com> --- drivers/usb/mtu3/mtu3_core.c | 2 -- drivers/usb/mtu3/mtu3_plat.c | 2 ++ 2 files changed, 2 insertions(+), 2 deletions(-)
