Subject: [PATCH 11/11] platform/x86: fujitsu-laptop: remove redundant fields from struct fujitsu_bl
Date: Thu, 30 Mar 2017 12:35:09 +0200	[thread overview]
Message-ID: <20170330103509.32509-12-kernel@kempniu.pl> (raw)
In-Reply-To: <20170330103509.32509-1-kernel@kempniu.pl>

The dev field of struct fujitsu_bl is assigned in acpi_fujitsu_bl_add(),
but never used afterwards.  brightness_changed is set in get_lcd_level()
and then its value is only printed in a debug message, so it does not
influence execution flow.  Remove both fields as they are redundant.
Update the aforementioned debug message.  Adjust whitespace to make
checkpatch happy.
