I get a few build warnings with this patch applied:

drivers/tty/serial/sc16is7xx.c:1059:12: warning: âsc16is7xx_probeâ defined but not used [-Wunused-function]
static int sc16is7xx_probe(struct device *dev,
^
drivers/tty/serial/sc16is7xx.c:1175:12: warning: âsc16is7xx_removeâ defined but not used [-Wunused-function]
static int sc16is7xx_remove(struct device *dev)
^
drivers/tty/serial/sc16is7xx.c:1214:29: warning: âregcfgâ defined but not used [-Wunused-variable]
static struct regmap_config regcfg = {
^

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