From: Guoqing Jiang <gqjiang@xxxxxxxx> commit e00164a0f000de893944981f41a568c981aca658 upstream. err_spi is used when SERIAL_SC16IS7XX_SPI is enabled, so make the label only available under SERIAL_SC16IS7XX_SPI option. Otherwise, the below warning appears. drivers/tty/serial/sc16is7xx.c:1523:1: warning: label ‘err_spi’ defined but not used [-Wunused-label] err_spi: ^~~~~~~ Signed-off-by: Guoqing Jiang <gqjiang@xxxxxxxx> Fixes: ac0cdb3d9901 ("sc16is7xx: missing unregister/delete driver on error in sc16is7xx_init()") Signed-off-by: Arnd Bergmann <arnd@xxxxxxxx> Cc: Guenter Roeck <linux@xxxxxxxxxxxx> Signed-off-by: Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx> --- drivers/tty/serial/sc16is7xx.c | 2 ++ 1 file changed, 2 insertions(+) --- a/drivers/tty/serial/sc16is7xx.c +++ b/drivers/tty/serial/sc16is7xx.c @@ -1524,10 +1524,12 @@ static int __init sc16is7xx_init(void) #endif return ret; +#ifdef CONFIG_SERIAL_SC16IS7XX_SPI err_spi: #ifdef CONFIG_SERIAL_SC16IS7XX_I2C i2c_del_driver(&sc16is7xx_i2c_uart_driver); #endif +#endif err_i2c: uart_unregister_driver(&sc16is7xx_uart); return ret;
