Subject[PATCH 4/4] leds: lp8501: make several arrays static const
Date
From: Colin Ian King <colin.king@canonical.com>

Don't populate the arrays on the stack, instead make them static const.
Makes the object code smaller by 50 bytes:

Before:
text data bss dec hex filename
5058 1552 64 6674 1a12 drivers/leds/leds-lp8501.o

After:
text data bss dec hex filename
4788 1776 64 6628 19e4 drivers/leds/leds-lp8501.o
