Thanks for re-posting this? (I don't recall If I actually posted the 
first time around).

But I actually have a small addendum for this series, as it will break 
`drivers/net/wwan/t7xx/t7xx_dpmaif.c` due to a redefinition (yeah I know).

So I have:
https://gitlab.com/olliver/linux/-/commit/c9e591f2dabb2dbaeceebee61fa70b70fdbffc2a
https://gitlab.com/olliver/linux/-/commit/41e0f8c08a1c55940813a240215910336ad7bec2
https://gitlab.com/olliver/linux/-/commit/f36562f09b0185d403415864ef7218b46a742cdc
https://gitlab.com/olliver/linux/-/commit/66237fd97bc42d272602b01dc0cca541c619b2be

Which actually replaces silly calls like readx_poll_timeout(ioread32, ... .

Do you want me to (re-?)post this as a series? I can put your 
thunderbolt (and your changes here) and post as one big series (or you 
can do the same obviously).
