From d618651b0f112d9715d0ca6f9dbea87761be15d7 Mon Sep 17 00:00:00 2001 From: David Herrmann Date: Wed, 21 Oct 2015 12:46:10 +0200 Subject: [PATCH] thinkpad_acpi: Don't yell on unsupported brightness interfaces The thinkpad_acpi driver currently emits error messages on unsupported brightness interfaces, giving the impression that someone will implement those. However, this error is spit out on nearly every thinkpad in production since 2 years now. Furthermore, the backlight interfaces on those devices are supported by the i915 driver just fine. Downgrade the error message to a normal pr_info() and stop telling people to report it to IBM.
