Use preferred of_device_get_match_data() instead of of_match_device() to
get the driver match data. With this, adjust the includes to explicitly
include the correct headers.

Perhaps device_get_match_data() could be used here and all the ACPI
specific code dropped, but not sure if all the ACPI code is really
necessary.

Nit: braces can be removed.

With or without nit fixed:

Coding style says otherwise when the 'else' has braces.

Hello Rob,

I know what the coding style says when the 'else' has braces.

I simply missed that there was an else with braces, since there was a
closing brace on a line by itself. The coding style says that the closing
brace should be on the same line as the 'else':
https://www.kernel.org/doc/html/latest/process/coding-style.html#placing-braces-and-spaces

But I guess that isn't followed because of the #ifdef CONFIG_ACPI.

I guess a better option would be to use if (IS_ENABLED(CONFIG_ACPI))
instead of #ifdef CONFIG_ACPI, but that is orthogonal to your change,
so let's ignore my nit. I've given my R-b tag on the patch already.


Kind regards,
Niklas

Applied to for-6.7. Thanks !
