Subject: [PATCH] platform/x86: acer-wmi: Silence "unsupported" message a bit
Date: Thu, 16 Aug 2018 09:27:10 +1000 [thread overview]
Message-ID: <7ccdc39d7e255547e851497ef9f449715b45f8bd.camel@kernel.crashing.org> (raw)
This driver prints that "Unsupported machine..." message on every boot on
ThinkPad X1 Carbon laptops (and I assume a number of other systems), which
causes graphical boots to "glitch" a bit and is rather annoying ...
Make it a pr_debug instead.
