When i2c-hid fails to read the HID report descriptor during device
initialization, the error message prints as:

  hid (null): reading report descriptor failed

The HID device name is set in hid_add_device() after calling
hdev->ll_driver->parse(), so when i2c_hid_parse() fails and calls
hid_err(), the device name has not been set yet, resulting in "(null)"
output.

Use dev_err(&client->dev, ...) instead of hid_err(hid, ...) because
the I2C client device is fully initialized with a proper name, providing
meaningful error messages for debugging.

Before: hid (null): reading report descriptor failed
After:  i2c_hid i2c-TPD0001:00: reading report descriptor failed
