[PATCH] serial: 8250: 8250_omap: make a const array static, makes object smaller

From: Colin King
Date: Thu Jul 15 2021 - 10:08:02 EST


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

Don't populate the const array k3_soc_devices on the stack but instead it
static. Makes the object code smaller by 44 bytes:

Before:
text data bss dec hex filename
31628 5609 128 37365 91f5 drivers/tty/serial/8250/8250_omap.o

After:
text data bss dec hex filename
31520 5673 128 37321 91c9 drivers/tty/serial/8250/8250_omap.o
Reduction of 44 bytes

(gcc version 10.3.0)
