Subject: backlight: lcd - Fix wrong sizeof

Which is why I have always preferred sizeof(struct foo) over
sizeof(var).

Subject: backlight: Fix backlight limiting on spitz/corgi devices

On spitz (& similar) machines, if battery is running low, backlight
needs
to be limited to lower step.  Unfortunately, current code uses &= for
limiting, turning backlight off completely for some backlight settings.
Fix that.

Subject: leds-gpio: fix possible crash on OF device unbinding

If there are leds present in the OF tree, but the GPIOs for (some) of
them are unavailable, led_data doesn't get populated with correct
devices. Then, on device unbinding, one can crash the kernel.

Workaround this by setting led->gpio to invalid value early.
