Subject: [PATCH v3 4/5] platform/x86: think-lmi: Don't display unnecessary authentication settings
Date: Fri, 26 May 2023 13:16:57 -0400	[thread overview]
Message-ID: <20230526171658.3886-4-mpearson-lenovo@squebb.ca> (raw)
In-Reply-To: <20230526171658.3886-1-mpearson-lenovo@squebb.ca>

If Opcode support is available (which is the standard for all platforms
going forward) then there is no need to have the encoding and kbdlang
attributes visible
