Merge patch series "scsi: Make use of bus callbacks"

Uwe Kleine-König <u.kleine-koenig@baylibre.com> says:

Hello,

this is v2 of the series to make the scsi subsystem stop using the
callbacks .probe(), .remove() and .shutdown() of struct device_driver.
Instead use their designated alternatives in struct bus_type.

The eventual goal is to drop the callbacks from struct device_driver.

The 2nd patch introduces some legacy handling for drivers still using
the device_driver callbacks. This results in a runtime warning (in
driver_register()). The following patches convert all in-tree drivers
(and thus fix the warnings one after another).
Conceptually this legacy handling could be dropped at the end of the
series, but I think this is a bad idea because this silently breaks
out-of-tree drivers (which also covers drivers that are currently
prepared for mainline submission) and in-tree drivers I might have
missed (though I'm convinced I catched them all). That convinces me that
keeping the legacy handling for at least one development cycle is the
right choice. I'll care for that at the latest when I remove the
callbacks from struct device_driver.
