[PATCH] backlight: fix pwm_bl.c when multiple PWM backlights exist

[PATCH] backlight: fix pwm_bl.c when multiple PWM backlights exist

[Eric Miao]

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.
