Subject: ACPI: device property: Switch to use new generic UUID API
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3689d3d6907271b5737de5bff584cb50cb29ebc2;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

ACPI: device property: Switch to use new generic UUID API

There are new types and helpers that are supposed to be used in new code.

As a preparation to get rid of legacy types and API functions do
the conversion here.
