Ricardo Ribalda Delgado a5cd98b796 leds-pca9633: Unique naming of the LEDs 
If there is more than one pca963x chips on the system and there are
some LEDs without platform_data names, the driver wont be able to
provide unique naming to them.

This will cause led_class_dev_register to fail, unregistering all the
LEDs of the chip.

This patch adds the i2c address to the name of the unnamed LEDs, making
them unique.
