Subject[PATCH v3 0/3] usb: core: lpm: add sysfs node for usb3 lpm permit
Date
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.

Change log:
v2->v3:
Make the code more readable by adding some comments and
refactoring the "if/else" code.

v1->v2:
Fix the "make htmldoc" warning reported by 0-day robot.

Thanks,
Baolu
