  soc/pxa: ssp: Convert to platform remove callback returning void (2023-10-14 23:27:34 +0200)

----------------------------------------------------------------
Convert drivers/soc to struct platform_driver::remove_new()

This PR contains the patches I sent in the series available at
https://lore.kernel.org/all/20230925095532.1984344-1-u.kleine-koenig@xxxxxxxxxxxxxx
that were not yet picked up in next as of next-20231013.

It converts all drivers below drivers/soc to let their remove callback
return void. See commit 5c5a7680e67b ("platform: Provide a remove
callback that returns no value") for the rationale.

Here comes the promised PR. The qcom patches are among the set of
patches dropped here as they are already in next.

To state the obvious: This is merge window material and the idea is that
it's pulled into armsoc and then included in the armsoc v6.7-rc1 PR to
Linus Torvalds. I hope it's not too late for that already.

Best regards and thanks
Uwe
