Hello Laurentiu Palcu,

The patch 4aeae9cb0dad: "power_supply: Add support for TI BQ25890
charger chip" from May 19, 2015, leads to the following static
checker warning:

	drivers/power/bq25890_charger.c:843 bq25890_probe()
	warn: impossible condition '(bq->chip_id < 0) => (0-255 < 0)'

drivers/power/bq25890_charger.c
   841  
   842          bq->chip_id = bq25890_field_read(bq, F_PN);
   843          if (bq->chip_id < 0) {
                    ^^^^^^^^^^^^^^^
Never true.

   844                  dev_err(dev, "Cannot read chip ID.\n");
   845                  return ret;
   846          }
   847
