From aa5c8b25392800bbefa82dd19eeff8ebbf261ace Mon Sep 17 00:00:00 2001 From: Jonathan Cameron Date: Thu, 3 Jun 2021 17:58:35 +0100 Subject: i2c: core: Add stub for i2c_verify_client() if !CONFIG_I2C If I2C is not compiled, there is no way we should see a call to i2c_verify_client() on a device that is an i2c client. As such, provide a stub to return NULL to resolve an associated build failure. The build is failing with this link error ld: fxls8962af-core.o: in function `fxls8962af_fifo_transfer': fxls8962af-core.c: undefined reference to `i2c_verify_client' Reported-by: Tom Rix Signed-off-by: Jonathan Cameron Fixes: af959b7b96b8 ("iio: accel: fxls8962af: fix errata bug E3 - I2C burst reads") Reviewed-by: Sean Nyekjaer Acked-by: Wolfram Sang Link: https://lore.kernel.org/r/20210603165835.3594557-1-jic23@kernel.org --- include/linux/i2c.h | 8 +++++++- 1 file changed, 7 insertions(+), 1 deletion(-) (limited to 'include/linux/i2c.h') diff --git a/include/linux/i2c.h b/include/linux/i2c.h index e8f2ac8c9c3d..7d71131c394e 100644 --- a/include/linux/i2c.h +++ b/include/linux/i2c.h @@ -343,7 +343,6 @@ struct i2c_client { }; #define to_i2c_client(d) container_of(d, struct i2c_client, dev) -struct i2c_client *i2c_verify_client(struct device *dev); struct i2c_adapter *i2c_verify_adapter(struct device *dev); const struct i2c_device_id *i2c_match_id(const struct i2c_device_id *id, const struct i2c_client *client); @@ -477,6 +476,13 @@ i2c_new_ancillary_device(struct i2c_client *client, u16 default_addr); void i2c_unregister_device(struct i2c_client *client); + +struct i2c_client *i2c_verify_client(struct device *dev); +#else +static inline struct i2c_client *i2c_verify_client(struct device *dev) +{ + return NULL; +} #endif /* I2C */ /* Mainboard arch_initcall() code should register all its I2C devices. -- cgit v1.2.3
