From e7562597b46d099a78d45c781ee8d1a7a93c53f1 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Tue, 29 Aug 2017 22:15:16 +0300 Subject: [PATCH] nfp: double free on error in probe Both the nfp_net_pf_app_start() and the nfp_net_pci_probe() functions call nfp_net_pf_app_stop_ctrl(pf) so there is a double free. The free should be done from the probe function because it's allocated there so I have removed the call from nfp_net_pf_app_start().
