[Stable-9.0.4 71/71] usb-hub: Fix handling port power control messages
Posted by Michael Tokarev 4 days, 21 hours ago
From: Guenter Roeck <linux@roeck-us.net>

The ClearPortFeature control message fails for PORT_POWER because there
is no break; at the end of the case statement, causing it to fall through
to the failure handler. Add the missing break; to solve the problem.

Fixes: 1cc403eb21 ("usb-hub: emulate per port power switching")
