linux.git/rust/helpers/acpi.c, branch master Linux kernel source tree rust: ACPI: fix missing match data for PRP0001 2026-04-28T18:28:28+00:00 Markus Probst markus.probst@posteo.de 2026-04-27T17:55:57+00:00 2690d071584ed8f488f2336f93272817b6999484 Export `acpi_of_match_device` function and use it to match the of device table against ACPI PRP0001 in Rust. This fixes id_info being None on ACPI PRP0001 devices. Using `device_get_match_data` is not possible, because Rust stores an index in the of device id instead of a data pointer. This was done this way to provide a convenient and obvious API for drivers, which can be evaluated in const context without the use of any unstable language features.

table against ACPI PRP0001 in Rust.
