From: Mathias Nyman Date: Thu, 30 Mar 2023 14:30:56 +0000 (+0300) Subject: xhci: Free the command allocated for setting LPM if we return early X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=f6caea4855553a8b99ba3ec23ecdb5ed8262f26c;p=linux.git xhci: Free the command allocated for setting LPM if we return early 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.
