The txx9ndfmc driver was fixed as part of this series, but Miquèl didn't
take the patch, I guess because he wants it to be converted to
module_platform_driver().

These two drivers were already covered in 20231001170254.2506508-1-u.kleine-koenig at pengutronix.de
where I also addressed a similar problem in the keystone driver.

These rtc drivers are fixed in 20231002080529.2535610-1-u.kleine-koenig at pengutronix.de

I sent 20231004111624.2667753-1-u.kleine-koenig at pengutronix.de to fix
a/drivers/platform/x86/hp/hp-wmi.c, that's already applied so doesn't
occur in your patch. The others I didn't address yet.

I assume your question means you want to push that forward. That is very
welcome, the I remove this from my todo list.

Best regards
Uwe
