Subject: [PATCH] backlight: fix pwm_bl.c when multiple PWM backlights exist
Date: Tue, 10 Feb 2009 13:30:37 +0800 [thread overview]
Message-ID: <499110FD.4030002@gmail.com> (raw)
When multiple PWMs are used as backlights, the current code uses
pdev->name as the backlight name when registering, which will be
conflicting, use dev_name() instead.
