X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=5a5754a4997c372292e57ed631807131c63cebaf;p=linux.git

nvme-pci: flush initial scan_work for async probe

The nvme device may have a namespace with the root partition, so make
sure we've completed scanning before returning from the async probe.

Fixes: eac3ef262941 ("nvme-pci: split the initial probe from the rest path")
