Subject[PATCH] watchdog: asm9260_wdt: make array mode_name static, shrinks object size
Date
From: Colin Ian King <colin.king@canonical.com>

Don't populate the const array mode_name on the stack but instead
make it static. Makes the object code smaller by 41 bytes:

Before:
text data bss dec hex filename
7699 1872 0 9571 2563 drivers/watchdog/asm9260_wdt.o

After:
text data bss dec hex filename
7594 1936 0 9530 253a drivers/watchdog/asm9260_wdt.o

(gcc version 8.2.0 x86_64)
