Subject: [PATCH 0/3] usb: core: lpm: add sysfs node for usb3 lpm permit
Date: Wed, 11 Nov 2015 16:03:23 +0800	[thread overview]
Message-ID: <1447229006-15011-1-git-send-email-baolu.lu@linux.intel.com> (raw)

Hi,

This patch series is about to add a sysfs attribute, through which
users can disable or enable USB3 LPM (link power management) from
a USB port. Once LPM is disabled from the USB port, LPM between the
downstreaming device and the hub port will not be activated. This
helps users to use any LPM-unfriendly USB devices on any released
Linux kernels.

This patch series contains a fix and a cleanup as well.

Thanks,
Baolu
