[RFC 06/22] sata: call device_probe() after scanning

AKASHI Takahiro takahiro.akashi at linaro.org
Fri Oct 1 07:01:56 CEST 2021


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.
