Subject[PATCH] regulator: lp8788-ldo: make array en_mask static const, makes object smaller
Date
From: Colin Ian King <colin.king@canonical.com>

Don't populate the array en_mask on the stack but instead make it
static const. Makes the object code smaller by 87 bytes.

Before:
text data bss dec hex filename
12967 3408 0 16375 3ff7 drivers/regulator/lp8788-ldo.o

After:
text data bss dec hex filename
12816 3472 0 16288 3fa0 drivers/regulator/lp8788-ldo.o

(gcc version 9.2.1, amd64)
