From eeef9150a174a030894fa159f675ba804ad90c06 Mon Sep 17 00:00:00 2001 From: David Wang <00107082@163.com> Date: Tue, 27 Aug 2024 07:34:37 +0800 Subject: ACPI: utils: Add rev/func to message when acpi_evaluate_dsm() fails When acpi_evaluate_dsm() fails, the warning message lacks the rev and func information which is available and helpful. For example, iwlwifi would make _DSM queries for lari config, and when it fails, all warning messages are all the same: ACPI: \: failed to evaluate _DSM bf0212f2-788f-c64d-a5b3-1f738e285ade (0x1001) ACPI: \: failed to evaluate _DSM bf0212f2-788f-c64d-a5b3-1f738e285ade (0x1001) ACPI: \: failed to evaluate _DSM bf0212f2-788f-c64d-a5b3-1f738e285ade (0x1001) ACPI: \: failed to evaluate _DSM bf0212f2-788f-c64d-a5b3-1f738e285ade (0x1001) ACPI: \: failed to evaluate _DSM bf0212f2-788f-c64d-a5b3-1f738e285ade (0x1001) ACPI: \: failed to evaluate _DSM bf0212f2-788f-c64d-a5b3-1f738e285ade (0x1001) ACPI: \: failed to evaluate _DSM bf0212f2-788f-c64d-a5b3-1f738e285ade (0x1001) ACPI: \: failed to evaluate _DSM bf0212f2-788f-c64d-a5b3-1f738e285ade (0x1001) With this change, the warnings would be more informative: ACPI: \: failed to evaluate _DSM bf0212f2-788f-c64d-a5b3-1f738e285ade rev:0 func:1 (0x1001) ACPI: \: failed to evaluate _DSM bf0212f2-788f-c64d-a5b3-1f738e285ade rev:0 func:6 (0x1001) ACPI: \: failed to evaluate _DSM bf0212f2-788f-c64d-a5b3-1f738e285ade rev:0 func:7 (0x1001) ACPI: \: failed to evaluate _DSM bf0212f2-788f-c64d-a5b3-1f738e285ade rev:0 func:8 (0x1001) ACPI: \: failed to evaluate _DSM bf0212f2-788f-c64d-a5b3-1f738e285ade rev:0 func:3 (0x1001) ACPI: \: failed to evaluate _DSM bf0212f2-788f-c64d-a5b3-1f738e285ade rev:0 func:9 (0x1001) ACPI: \: failed to evaluate _DSM bf0212f2-788f-c64d-a5b3-1f738e285ade rev:0 func:10 (0x1001) ACPI: \: failed to evaluate _DSM bf0212f2-788f-c64d-a5b3-1f738e285ade rev:0 func:12 (0x1001) Signed-off-by: David Wang <00107082@163.com> Link: https://patch.msgid.link/20240826233437.19632-1-00107082@163.com [ rjw: Subject and changelog edits ] Signed-off-by: Rafael J.
