Subject[PATCH 3/4] leds: lp5562: 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 over 150 bytes:

Before:
text data bss dec hex filename
7725 2448 64 10237 27fd drivers/leds/leds-lp5562.o

After:
text data bss dec hex filename
7184 2832 64 10080 2760 drivers/leds/leds-lp5562.o
