Please change this to make it clearer what the intended logic is (assuming it's not buggy) - something like if ... else if ... else for example. > + ret = regmap_read(pfuze_chip->regmap, PFUZE100_REVID, &value); > + if (ret) > + return ret; > + dev_info(pfuze_chip->dev, > + "Full lay: %x ,Metal lay: %x\n", > + (value & 0xf0) >> 4, value & 0x0f); The space should be after not before the comma in the displayed string. > + dev_info(pfuze_chip->dev, "FAB: %x , FIN: %x\n", > + (value & 0xc) >> 2, value & 0x3); Only a space after the , for normal formatting. ie both should look like "%x, bar".
