[PATCH] xhci: Free the command allocated for setting LPM if we return early

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

 



The command allocated to set exit latency LPM values need to be freed in
case the command is never queued. This would be the case if there is no
change in exit latency values, or device is missing.

Fixes: 5c2a380a5aa8 ("xhci: Allocate separate command structures for each LPM command")
