Subject: [PATCH -next] watchdog: sb_wdog: Make sbwdog_set and sbwdog_pet static

From: YueHaibing <yuehaibing@...wei.com>

Fix sparse warning:

drivers/watchdog/sb_wdog.c:70:6: warning: symbol 'sbwdog_set' was not declared. Should it be static?
drivers/watchdog/sb_wdog.c:84:6: warning: symbol 'sbwdog_pet' was not declared. Should it be static?
