First three patches are removing ACPI workarounds which should have never landed. The last four are adding a workaround to nouveau which seem to help quite a lot with the RTD3 issues with Nouveau, so let's discuss and get wider testing of those and see if there is any fallout or laptops where the issues don't get fixed. Karol Herbst (7): Revert "ACPI / OSI: Add OEM _OSI string to

acpi_evaluate_dsm() and friends take a pointer to a raw buffer of 16 bytes. Instead we convert them to use uuid_le type. At the same time we convert current users. acpi_str_to_uuid() becomes useless after the conversion and it's safe to get rid of it. The conversion fixes a potential bug in int340x_thermal as well since we have to use memcmp() on binary data. Cc: Rafael J.
