Hi Xenia,
thank you. I tested this patch on 3.11 kernel and the messages don't appear
anymore
upon LPM-capable device disconnect (tested with ASMedia AS2105 devices).
Not much to show here, there is just no error/warning related to LPM
while handling these devices.
Probably better test is with Prolific-based device for which I get during
connect:
[ 999.906164] usb 4-2.1: new SuperSpeed USB device number 20 using xhci_hcd

and during disconnect kernel is also quiet and doesn't complain anymore about
the
LPM of already disconnected device:
[ 1582.039612] usb 4-2.1: USB disconnect, device number 20
I think your patch works correctly and has shutdown the bogus/annoying
message. ;-)
Thank you.
Martin
