[PATCH 1/4] leds: aat1290: make array max_mm_current_percent static const

From: Colin King
Date: Thu Aug 24 2017 - 09:01:42 EST


From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

Don't populate the array max_mm_current_percent on the stack, instead
make it static const. Makes the object code smaller by over 280 bytes:

Before:
text data bss dec hex filename
7225 1936 64 9225 2409 ./drivers/leds/leds-aat1290.o

After:
text data bss dec hex filename
6847 2032 64 8943 22ef ./drivers/leds/leds-aat1290.o`
