From bdf2752305af1f8c2c2422ae2b292194cf33f5e9 Mon Sep 17 00:00:00 2001 From: Jacob Keller Date: Thu, 17 May 2018 01:08:32 -0700 Subject: [PATCH] i40e: free skb after clearing lock in ptp_stop Use the same logic to free the skb after clearing the Tx timestamp bit lock in i40e_ptp_stop as we use in the other locations. It is not as important here since we are not racing against a future Tx timestamp request (as we are disabling PTP at this point). However it is good to be consistent in how we approach the bit lock so that future callers don't copy the old anti-pattern.
