Subject: [PATCH 2/2] platform/chrome: Use imperative mood for ChromeOS ACPI sysfs ABI descriptions

From: Bagas Sanjaya <[email-masked]>
Date: Wed, 18 May 2022 10:17:51 +0700

The current descriptions all begin with ("This file shows something")
clause, which is incorrect wording since these mean return value from
sysfs.

Use imperative mood ("Returns something") instead, in line with
corresponding ACPI documentation at firmware-guide/.
