From 75c724e2b714215c0c101e1cc301e41001ee234c Mon Sep 17 00:00:00 2001 From: Michal Schmidt Date: Thu, 10 Aug 2023 17:01:12 +0200 Subject: [PATCH] octeon_ep: cancel tx_timeout_task later in remove sequence [ Upstream commit 28458c80006bb4e993a09fc094094a8578cad292 ] tx_timeout_task is canceled too early when removing the driver. Nothing prevents .ndo_tx_timeout from triggering and queuing the work again. Better cancel it after the netdev is unregistered. It's harmless for octep_tx_timeout_task to run in the window between the unregistration and cancelation, because it checks netif_running.
