[PATCH] hwmon: (w83793): make const array watchdog_minors static, reduces object code size

From: Colin King
Date: Fri Sep 22 2017 - 10:36:47 EST


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

Don't populate const array watchdog_minors on the stack, instead make it
static. Makes the object code smaller by over 350 bytes:

Before:
text data bss dec hex filename
48019 38144 256 86419 15193 drivers/hwmon/w83793.o

After:
text data bss dec hex filename
47574 38232 256 86062 1502e drivers/hwmon/w83793.o

(gcc 6.3.0, x86-64)
