Yes, it will. It also looks like there are some whitespace changes in the patch, unless of course that's just Git playing tricks!

NAK. It prevents using DT-enabled drivers on ACPI based platforms. +Cc: Jonathan who had done the opposite in the entire IIO subsystem.

And a side note: use of_match_ptr() and ACPI_PTR() in 99% is a mistake.

So a system without CONFIG_OF might still make use of .of_match_table? If so: TIL ... Best regards Uwe

Not the process of ACPI using OF artifacts or the possibilty to embed OF type structures into ACPI tables, but the fact that an OF-only user (or so they think) should have to care about that special use-case. What if we make ACPI select OF? Or handle the ACPI case explicitly in the of_match_ptr() declaration?

OF-only users shouldn't take care about this. If you are sure that the driver may not be used on a non-OF platform. > What if we make ACPI select OF? Or handle the ACPI case explicitly in > the of_match_ptr() declaration? I guess you are a bit late, but you always may propose patches to ACPI maintainers.

If ACPI now can contain OF pieces, we should ask the question whether of_match_ptr() should be used at all. Would it be a compromise introducing a new macro (eg. "OF_MATCH_PTR()") which passes through the pointer if either OF or ACPI is enabled. Maybe we could introduce a new config item (eg "OF_MATCH_TABLE") for that, which is enabled by both OF and ACPI. And maybe add an option for of-compatible checking in ACPI. How do you folks think about that ? --mtx

The of_match_ptr(foo) macro evaluates to foo, only if CONFIG_OF is set, otherwise to NULL. Same does ACPI_PTR with CONFIG_ACPI. That's very helpful for drivers that can be used with or without oftree / acpi. Even though most of the drivers touched here probably don't actually need that, it's also nice for consistency to make it the de-facto standard and change all drivers to use the of_match_ptr() and ACPI_PTR() macros. A nice side effect: in some situations, when compiled w/o CONFIG_OF/CONFIG_ACPI, the corresponding match tables could automatically become unreferenced and optimized-away by the compiler, w/o explicitly cluttering the code w/ ifdef's.
