From 46182452cf5abe95782e100f0719b7497641d263 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Thu, 22 Feb 2018 12:44:40 +0100 Subject: [PATCH] dsa: ptp: mark dummy helpers as 'inline' Declaring a static function in a header leads to a warning every time that header gets included without the function being used: In file included from drivers/net/dsa/mv88e6xxx/chip.c:42: drivers/net/dsa/mv88e6xxx/ptp.h:92:13: error: 'mv88e6xxx_hwtstamp_work' defined but not used [-Werror=unused-function] static long mv88e6xxx_hwtstamp_work(struct ptp_clock_info *ptp) In file included from drivers/net/dsa/mv88e6xxx/chip.c:38: drivers/net/dsa/mv88e6xxx/global2.h:355:12: error: 'mv88e6xxx_g2_wait' defined but not used [-Werror=unused-function] static int mv88e6xxx_g2_wait(struct mv88e6xxx_chip *chip, int reg, u16 mask) ^~~~~~~~~~~~~~~~~ drivers/net/dsa/mv88e6xxx/global2.h:350:12: error: 'mv88e6xxx_g2_update' defined but not used [-Werror=unused-function] static int mv88e6xxx_g2_update(struct mv88e6xxx_chip *chip, int reg, u16 update) ^~~~~~~~~~~~~~~~~~~ drivers/net/dsa/mv88e6xxx/global2.h:345:12: error: 'mv88e6xxx_g2_write' defined but not used [-Werror=unused-function] static int mv88e6xxx_g2_write(struct mv88e6xxx_chip *chip, int reg, u16 val) ^~~~~~~~~~~~~~~~~~ drivers/net/dsa/mv88e6xxx/global2.h:340:12: error: 'mv88e6xxx_g2_read' defined but not used [-Werror=unused-function] static int mv88e6xxx_g2_read(struct mv88e6xxx_chip *chip, int reg, u16 *val) This marks all such functions in dsa inline to make sure we don't warn about them.
