Currently, for a TLV consisting of TLV_DB_SCALE_ITEMs, if e.g. alsamixer calls snd_mixer_selem_set_playback_dB() with a value that is in-between two TLV_DB_SCALE_ITEMs, and xdir is negative, the selected raw hardware value is the minimum in the first range above that value, rather than the maximum in the last range below that value. The user-visible symptom is that in alsamixer, pressing the down key to reduce the value sticks at certain points, and cannot be incrementally reduced any further, although directly selecting a much lower value (e.g. by pressing 0..9) works as expected. This is triggered e.g. by sound/soc/codec/max98090.c's max98090_hp_tlv[]. Fix this by checking whether xdir is positive or not, rather than checking whether it has a non-zero value. The code to select the previous range's max value is already present. This matches how xdir is used in other parts of the code.
