I get a few build warnings with this patch applied:

drivers/tty/serial/sc16is7xx.c:1059:12: warning: ‘sc16is7xx_probe’ defined but not used [-Wunused-function]
 static int sc16is7xx_probe(struct device *dev,
            ^
drivers/tty/serial/sc16is7xx.c:1175:12: warning: ‘sc16is7xx_remove’ defined but not used [-Wunused-function]
 static int sc16is7xx_remove(struct device *dev)
            ^
drivers/tty/serial/sc16is7xx.c:1214:29: warning: ‘regcfg’ defined but not used [-Wunused-variable]
 static struct regmap_config regcfg = {
                             ^

Can you send a follow-on patch to fix them?
