Hello,

this series is part of an effort to get rid of the .shutdown() callback
(and .probe() and .remove()) in struct device_driver. Preparing that,
all sdio drivers that up to now use this callback are converted to a new
sdio specific shutdown callback.

Patch #2 is just a cleanup I noticed while working on
drivers/net/wireless/rsi/rsi_91x_sdio.c. Note that it's uncommon to have
the shutdown callback conditionalized by #ifdef CONFIG_PM. I guess this
dependency was introduced by mistake in commit 063848c3e155 ("rsi: sdio:
Add WOWLAN support for S5 shutdown state"), but I didn't address it
here.

Patches #3 and #4 depend on the first patch, and with just the first
patch applied there is a runtime warning (emitted by the driver core in
driver_register()) for each unconverted driver. So it would be nice to
get the whole series in during a single merge window to not let users
face the warning.

This series was build tested on amd64 and arm64 using allmodconfig.

Best regards
Uwe
