From fa70045e9df47d2e7a698e5f7a0d21423a58cdaa Mon Sep 17 00:00:00 2001 From: Heikki Krogerus Date: Thu, 12 Nov 2015 15:21:23 +0200 Subject: serial: 8250_mid: Add missing dependency 8250_mid uses rational_best_approximation() function, so the driver needs to select CONFIG_RATIONAL option. This fixes build error when CONFIG_RATIONAL is not enabled: drivers/built-in.o: In function `mid8250_set_termios': 8250_mid.c:(.text+0x10169a): undefined reference to `rational_best_approximation' Reported-by: Randy Dunlap Signed-off-by: Heikki Krogerus Acked-by: Andy Shevchenko Signed-off-by: Arnd Bergmann Signed-off-by: Greg Kroah-Hartman --- drivers/tty/serial/8250/Kconfig | 1 + 1 file changed, 1 insertion(+) diff --git a/drivers/tty/serial/8250/Kconfig b/drivers/tty/serial/8250/Kconfig index e6f5e12a2d83..6412f1455beb 100644 --- a/drivers/tty/serial/8250/Kconfig +++ b/drivers/tty/serial/8250/Kconfig @@ -373,6 +373,7 @@ config SERIAL_8250_MID depends on SERIAL_8250 && PCI select HSU_DMA if SERIAL_8250_DMA select HSU_DMA_PCI if X86_INTEL_MID + select RATIONAL help Selecting this option will enable handling of the extra features present on the UART found on Intel Medfield SOC and various other -- cgit v1.2.3-55-g7522
