When reading temperature or humidity values, a shift of two bits to the right needs to be applied, and only for the humidity channel a mask of the lower 12 bits needs to be applied. This reduces code repetition. During probe, i2c_set_clientdata() was used, although its counterpart was not, so drop it.
