The warning complains about a device being released with MSI descriptors
still attached to the device. This was added by:
5b012cede0f7 ("device: Add device::msi_data pointer and struct
msi_device_data")
That's not a regression caused by this commit. The warning is just
exposing an already existing problem in the iwlwifi driver, which seems
to do:
probe()
setup_pci_msi[x]_interrupts()
start_drv()
if (try_to_load_firmware() == FAIL)
device_release_driver()
...
msi_device_data_release()
WARN()
Thanks,
