[RFC 05/22] sata: call device_probe() after scanning

AKASHI Takahiro
2021-10-01T05:04:52Z

Every time a sata bus/port is scanned and a new device is detected,
we want to call device_probe() as it will give us a chance to run additional
post-processings for some purposes.

In particular, support for creating partitions on a device will be added.
