Subject[PATCH v2 0/9] i2c: move handling of suspended adapters to the core
Date
Here is the new version without specific I2C helpers but using the
'is_suspended' flag from the PM core. I didn't like messing with the
flag directly, so I did a helper in patch 1. So far, I like the
approach. The diffstat looks nice, and i2c-rcar.c and i2c-sh_mobile.c
rejected rightfully too later transfers without further modifications.
Tested on a Renesas Lager board (R-Car H2).

I dropped a few Tested-by tags because I think this approach is too
different from V1 to keep them. I hope you guys can have a look again.
Thanks for all the testing, so far!

A branch can be found here:

git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux.git renesas/i2c/reject-when-suspended

If this series is acceptable, I'd suggest to take it via my i2c tree
after rc1. And then I'll provide an immutable branch for the PM tree to
pick. Let me know if this works for you.

And thanks to Renesas for funding this work!

Thanks and kind regards,

Wolfram
