Date: Sat, 13 Oct 2012 04:41:25 +0400 From: Igor Murzov <e-mail@...e.by> To: linux-acpi@...r.kernel.org Cc: Zhang Rui <rui.zhang@...el.com>, Len Brown <lenb@...nel.org>, Stefan Wilkens <stefanwilkens@...il.com>, Sergey V <sftp.mtuci@...il.com>, linux-kernel@...r.kernel.org, Igor Murzov <e-mail@...e.by> Subject: [PATCH] ACPI video: Ignore errors after _DOD evaluation. There are systems where video module known to work fine regardless of broken _DOD and ignoring returned value here doesn't cause any issues later. This should fix brightness controls on some laptops.
