[PATCH 7/7] usbnet: qmi_wwan: don't recover device if suspend fails in system sleep

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



If suspend callback fails in system sleep context, usb core will
ignore the failure and let system sleep go ahead further, so
this patch doesn't recover device under this situation.
