Subject: [PATCH] i40e: fix uninitialized variable in i40e_set_vsi_promisc
Date: Wed, 12 Aug 2020 16:39:50 +0200	[thread overview]
Message-ID: <20200812143950.11675-1-sassmann@kpanic.de> (raw)

drivers/net/ethernet/intel/i40e/i40e_virtchnl_pf.c: In function ‘i40e_set_vsi_promisc’:
drivers/net/ethernet/intel/i40e/i40e_virtchnl_pf.c:1176:14: error: ‘aq_ret’ may be used uninitialized in this function [-Werror=maybe-uninitialized]
  i40e_status aq_ret;

In case the code inside the if statement and the for loop does not get
executed aq_ret will be uninitialized when the variable gets returned at
the end of the function.

Fixes: 37d318d7805f ("i40e: Remove scheduling while atomic possibility")
