| |
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)
