Subject: [PATCH] platform/x86: ideapad-laptop: fix method name typo
Date: Fri, 07 May 2021 23:53:44 +0000	[thread overview]
Message-ID: <20210507235333.286505-1-pobrn@protonmail.com> (raw)

"smbc" should be "sbmc". `eval_smbc()` incorrectly called
the SMBC ACPI method instead of SBMC. This resulted in
partial loss of functionality. Rectify that by calling
the correct ACPI method (SBMC), and also rename
methods and constants.

BugLink: https://bugzilla.kernel.org/show_bug.cgi?id=212985
Fixes: 0b765671cb80 ("platform/x86: ideapad-laptop: group and separate (un)related constants into enums")
Fixes: ff36b0d953dc ("platform/x86: ideapad-laptop: rework and create new ACPI helpers")
Cc: stable@vger.kernel.org # 5.12
