I made a mistake on the latest patch I sent, 

if (IS_ERR(bllcd->lcd_device)) {
+               ret = PTR_ERR(bllcd->bl_device);
+               backlight_device_unregister(bllcd->bl_device);
+               printk(KERN_ERR "lcd :failed to register device\n");
+               kfree(bllcd);
+               return ret;
+       }

should ofcourse read

if (IS_ERR(bllcd->lcd_device)) {
+               ret = PTR_ERR(bllcd->lcd_device);
+               backlight_device_unregister(bllcd->bl_device);
+               printk(KERN_ERR "lcd :failed to register device\n");
+               kfree(bllcd);
+               return ret;
+       }

Its fixed now for me. Going to test that mdelay issue now.
