Subject[PATCH] regulator: rt6245: make a const array func_base static, makes object smaller
Date
From: Colin Ian King <colin.king@canonical.com>

Don't populate the const array func_base on the stack but instead it
static. Makes the object code smaller by 55 bytes:

Before:
text data bss dec hex filename
6422 3216 64 9702 25e6 drivers/regulator/rt6245-regulator.o

After:
text data bss dec hex filename
6303 3280 64 9647 25af drivers/regulator/rt6245-regulator.o

Reduction of 55 bytes

(gcc version 10.3.0)
