From e89d67cfbcc1ee32339da9e816489f69742c3a6e Mon Sep 17 00:00:00 2001 From: Rakib Mullick Date: Wed, 27 Oct 2010 15:34:26 -0700 Subject: [PATCH] drivers/char/mxser.c: fix compilation warning in mxser.c Both mxser_disable_must_enchance_mode() and mxser_get_must_hardware_id() called from function CheckIsMoxaMust(), when CONFIG_PCI=y. So mark both the functions under CONFIG_PCI. We were warned by the following warning. drivers/char/mxser.c:306: warning: `mxser_disable_must_enchance_mode' defined but not used drivers/char/mxser.c:391: warning: `mxser_get_must_hardware_id' defined but not used Signed-off-by: Rakib Mullick Cc: Jiri Slaby Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- drivers/char/mxser.c | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/drivers/char/mxser.c b/drivers/char/mxser.c index 463df27..dd9d753 100644 --- a/drivers/char/mxser.c +++ b/drivers/char/mxser.c @@ -303,6 +303,7 @@ static void mxser_enable_must_enchance_mode(unsigned long baseio) outb(oldlcr, baseio + UART_LCR); } +#ifdef CONFIG_PCI static void mxser_disable_must_enchance_mode(unsigned long baseio) { u8 oldlcr; @@ -317,6 +318,7 @@ static void mxser_disable_must_enchance_mode(unsigned long baseio) outb(efr, baseio + MOXA_MUST_EFR_REGISTER); outb(oldlcr, baseio + UART_LCR); } +#endif static void mxser_set_must_xon1_value(unsigned long baseio, u8 value) { @@ -388,6 +390,7 @@ static void mxser_set_must_enum_value(unsigned long baseio, u8 value) outb(oldlcr, baseio + UART_LCR); } +#ifdef CONFIG_PCI static void mxser_get_must_hardware_id(unsigned long baseio, u8 *pId) { u8 oldlcr; @@ -404,6 +407,7 @@ static void mxser_get_must_hardware_id(unsigned long baseio, u8 *pId) *pId = inb(baseio + MOXA_MUST_HWID_REGISTER); outb(oldlcr, baseio + UART_LCR); } +#endif static void SET_MOXA_MUST_NO_SOFTWARE_FLOW_CONTROL(unsigned long baseio) { -- 2.7.4
