Subject: [PATCH v2 08/11] platform/x86: fujitsu-laptop: ignore errors when setting backlight power
Date: Wed,  5 Apr 2017 08:49:07 +0200	[thread overview]
Message-ID: <20170405064910.3162-9-kernel@kempniu.pl> (raw)
In-Reply-To: <20170405064910.3162-1-kernel@kempniu.pl>

Not all Fujitsu laptops support controlling backlight power through the
FUJ02E3 ACPI device.  Remove the debug message informing about a failed
attempt to set backlight power as it may be confusing and the return
value of call_fext_func() is logged anyway.
