There are two issues in nvme_pci_enable(): 1) If pci_alloc_irq_vectors() fails, device is left enabled. Fix this by adding a goto disable statement. 2) nvme_pci_configure_admin_queue could return -ENODEV, in this case, we will need to free IRQ properly. Otherwise the following warning could be triggered: [ 5.286752] WARNING: CPU: 0 PID: 33 at kernel/irq/irqdomain.c:253 irq_domain_remove+0x12d/0x140 [ 5.290547] Call Trace: [ 5.290626] <TASK> [ 5.290695] msi_remove_device_irq_domain+0xc9/0xf0 [ 5.290843] msi_device_data_release+0x15/0x80 [ 5.290978] release_nodes+0x58/0x90 [ 5.293788] WARNING: CPU: 0 PID: 33 at kernel/irq/msi.c:276 msi_device_data_release+0x76/0x80 [ 5.297573] Call Trace: [ 5.297651] <TASK> [ 5.297719] release_nodes+0x58/0x90 [ 5.297831] devres_release_all+0xef/0x140 [ 5.298339] device_unbind_cleanup+0x11/0xc0 [ 5.298479] really_probe+0x296/0x320 Fixes: a6ee7f19 ("nvme-pci: call nvme_pci_configure_admin_queue from nvme_pci_enable") Co-developed-by:
