If anyone has any objections, please let me know. ------------------ From: Takashi Iwai commit 468ac413045af1e0e4d1272291bed6878f248a69 upstream. We don't change the EAPD bit in set_pin_eapd() if keep_eapd_on flag is set by the codec driver and enable is false. But, we also apply the flipping of enable value according to inv_eapd flag in the same function, and this confused the former check, handled as if it's turned ON. The inverted EAPD check must be applied after keep_eapd_on check, instead.
