Subject: [PATCH 5.6 057/126] ALSA: hda/realtek - Add HP new mute led supported for ALC236

From: Kailang Yang <kailang@...ltek.com>

[ Upstream commit 24164f434dc9c23cd34fca1e36acea9d0581bdde ]

HP new platform has new mute led feature.
COEF index 0x34 bit 5 to control playback mute led.
COEF index 0x35 bit 2 and bit 3 to control Mic mute led.

[ corrected typos by tiwai ]
