Hi Bart,

I haven't actually tested the code yet (but will do so this week). But I
already want to feed back that I approve of the general concept of
abstracting away drivers access to the struct device by something we can
then convert to SRCU in a central place.

This mail is to discuss the timeline of these series. My preferred
solution is to aim for inclusion right after 7.0-rc1 is released. That
gives me enough time to test and you some more time to address review
comments. Bold wish, but maybe we can even get dependencies into 6.19
before (like the i2c_dbg rename for the saa7134 driver. Is there a patch
for it already?).

Does that work for you?

Happy hacking and thanks again for doing all this!
