The AT24 EEPROM driver does not initialise the 'id' field of the nvmem_config structure and because the entire structure is not initialised, it ends up with a random value. This causes the NVMEM driver to append the device 'devid' value to name of the NVMEM device. Although this is not a problem per-se, for I2C devices such as the AT24, that already have a device unique name, there does not seem much value in appending an additional 0 to the I2C name. For example, appending a 0 to an I2C device name such as 1-0050 does not seem necessary and maybe even a bit confusing. Therefore, fix this by setting the NVMEM config.id to NVMEM_DEVID_NONE for AT24 EEPROMs. Signed-off-by: Jon Hunter <jonathanh@xxxxxxxxxx> --- drivers/misc/eeprom/at24.c | 1 + 1 file changed, 1 insertion(+) diff --git a/drivers/misc/eeprom/at24.c b/drivers/misc/eeprom/at24.c index e9df1ca251df..3f7a3bb6a36c 100644 --- a/drivers/misc/eeprom/at24.c +++ b/drivers/misc/eeprom/at24.c @@ -715,6 +715,7 @@ static int at24_probe(struct i2c_client *client) nvmem_config.name = dev_name(dev); nvmem_config.dev = dev; + nvmem_config.id = NVMEM_DEVID_NONE; nvmem_config.read_only = !writable; nvmem_config.root_only = !(flags & AT24_FLAG_IRUGO); nvmem_config.owner = THIS_MODULE; -- 2.25.1
