Subject: ALSA: hda/realtek: Enable front panel headset LED on Lenovo ThinkStation P520
From: Kai-Heng Feng <kai.heng.feng@xxxxxxxxxxxxx>
commit f73bbf639b32acb6b409e188fdde5644b301978f upstream.
On Lenovo P520, the front panel headset LED isn't lit up right now.
Realtek states that the LED needs to be enabled by ALC233's GPIO2, so
let's do it accordingly to light the LED up.
