nit:

If you have to respin for some other reason, please consider limiting lines
to 80 columns wide or less here and elsewhere in this patch where it
doesn't reduce readability (subjective I know).

e.g.:

static void print_sensor_names_in_bit_set(struct mlx5_core_dev *dev,
                                          struct mlx5_hwmon *hwmon,
                                          u64 bit_set, int bit_set_offset)
{
        unsigned long *bit_set_ptr = (unsigned long *)&bit_set;
        int num_bits = sizeof(bit_set) * BITS_PER_BYTE;
        int i;

        for_each_set_bit(i, bit_set_ptr, num_bits) {
                const char *sensor_name;

                sensor_name = hwmon_get_sensor_name(hwmon, i + bit_set_offset);

                mlx5_core_warn(dev, "Sensor name[%d]: %s\n",
                               i + bit_set_offset, sensor_name);
        }
}
