From: Alex Hung Date: Wed, 14 Oct 2020 01:03:40 +0000 (-0600) Subject: ACPI: processor: remove comment regarding string _UID support X-Git-Tag: v5.10.7~1327^2^4 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=d85cc6635a2a1338f7a45f652e97b02f9a69b9f5;p=platform%2Fkernel%2Flinux-rpi.git ACPI: processor: remove comment regarding string _UID support ACPI 6.3 Errata A no longer allows _UID to return a string except for Itanium (for historical reasons) as stated in section 5.2.12: "From ACPI Specification 6.3 onward, all processor objects for all architectures except Itanium must now use Device() objects with an _HID of ACPI0007, and use only integer _UID values." Therefore, the "we don't handle string _UIDs yet" comment, which implies a missing feature, is redundant, so drop it.
