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 <trix@redhat.com> Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com> Fixes: af959b7b96b8 ("iio: accel: fxls8962af: fix errata bug E3 - I2C burst reads") Reviewed-by: Sean Nyekjaer <sean@geanix.com> Acked-by: Wolfram Sang <wsa@kernel.org> Link: https://lore.kernel.org/r/20210603165835.3594557-1-jic23@kernel.org
