Subject: rust: platform: Set `OF_ID_TABLE` default to `None` in `Driver` trait
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ec3ef2175e16360605c7e1b409ceaa77be6521a8;p=thirdparty%2Fkernel%2Fstable.git

rust: platform: Set `OF_ID_TABLE` default to `None` in `Driver` trait

Provide a default value of `None` for `Driver::OF_ID_TABLE` to simplify
driver implementations.

Drivers that do not require OpenFirmware matching no longer need to
import the `of` module or define the constant explicitly.

This reduces unnecessary boilerplate and avoids pulling in unused
dependencies.
