backlight: lm3639: Unconditionally call led_classdev_unregister
Clang warns that the address of a pointer will always evaluated as true in a boolean context. drivers/video/backlight/lm3639_bl.c:403:14: warning: address of 'pchip->cdev_torch' will always evaluate to 'true' [-Wpointer-bool-conversion] if (&pchip->cdev_torch) ~~ ~~~~~~~^~~~~~~~~~ drivers/video/backlight/lm3639_bl.c:405:14: warning: address of 'pchip->cdev_flash' will always evaluate to 'true' [-Wpointer-bool-conversion] if (&pchip->cdev_flash) ~~ ~~~~~~~^~~~~~~~~~ 2 warnings generated. These statements have been present since 2012, introduced by commit 0f59858d5119 ("backlight: add new lm3639 backlight driver"). Given that they have been called unconditionally since then presumably without any issues, removing the always true if statements to fix the warnings without any real world changes.
