Subject: [PATCH 2/2] backlight: Fix blanking for L4F00242T03 LCD
Date: Fri, 4 Jun 2010 07:52:28 +0200 [thread overview]
Message-ID: <1275630748-10722-2-git-send-email-marek.vasut@gmail.com> (raw)
In-Reply-To: <1275630748-10722-1-git-send-email-marek.vasut@gmail.com>
The LCD was turned on if the variable power was > 0, but that was incorrect. The
LCD has to be turned on in every case but POWERDOWN.
