From 4d88c339c423eefe2fd48215016cb0c75fcb4c4d Mon Sep 17 00:00:00 2001 From: Sudarsana Reddy Kalluru Date: Thu, 23 Sep 2021 03:16:05 -0700 Subject: [PATCH] atlantic: Fix issue in the pm resume flow. After fixing hibernation resume flow, another usecase was found which should be explicitly handled - resume when device is in "down" state. Invoke aq_nic_init jointly with aq_nic_start only if ndev was already up during suspend/hibernate. We still need to perform nic_deinit() if caller requests for it, to handle the freeze/resume scenarios. Fixes: 57f780f1c433 ("atlantic: Fix driver resume flow.")
