SubjectRe: [RFC] hwmon: ina2xx: port to using remap, improve bandwidth.
Hi Marc,

[auto build test WARNING on hwmon/hwmon-next -- if it's inappropriate base, please suggest rules for selecting the more suitable base]

url: https://github.com/0day-ci/linux/commits/Marc-Titinger/hwmon-ina2xx-port-to-using-remap-improve-bandwidth/20151024-001809
config: x86_64-randconfig-x011-10211707 (attached as .config)
reproduce:
# save the attached .config to linux build tree
make ARCH=x86_64

All warnings (new ones prefixed by >>):

drivers/hwmon/ina2xx.c: In function 'ina2xx_probe':
>> drivers/hwmon/ina2xx.c:456:16: warning: format '%li' expects argument of type 'long int', but argument 3 has type 'u32 {aka unsigned int}' [-Wformat=]
dev_err(dev, "Invalid shunt resistor value %li", val);
^

vim +456 drivers/hwmon/ina2xx.c

440 /* Set config according to device type. */
441 data->config = &ina2xx_config[id->driver_data];
442 data->client = client;
443
444 /* Check for shunt resistor value.
445 * Give precedence to device tree over must-recompile.
446 */
447 if (of_property_read_u32(dev->of_node, "shunt-resistor", &val) < 0) {
448 pdata = dev_get_platdata(dev);
449 if (pdata)
450 val = pdata->shunt_uohms;
451 else
452 val = INA2XX_RSHUNT_DEFAULT;
453 }

457 return -ENODEV;
458 }
459 data->rshunt = val;
460
461 /* Write config to chip, and calibrate */
462 ret = ina2xx_init(data);
463 if (ret) {
