Subsequent i40e_shutdown() called during shutdown/reboot dereferences NULL pointer as pci_get_drvdata() returns NULL. To fix call pci_set_drvdata() also during entering to recovery mode. Reproducer: 1) Lets have i40e NIC with firmware in recovery mode 2) Run reboot Result: [ 139.084698] i40e: Intel(R) Ethernet Connection XL710 Network Driver [ 139.090959] i40e: Copyright (c) 2013 - 2019 Intel Corporation.
