[PATCH] ALSA: hda/realtek: Use inverted mute LED quirk for HP ZBook 8 G2a

[Chris Chiu]

HP ZBook 8 G2a (SSIDs 0x103c:0x8f40, 0x103c:0x8f41, 0x103c:0x8f42,
0x103c:0x8f62) use the Realtek ALC245 codec with a TAS2781 amplifier
via I2C. They share the same hardware configuration as the related
0x103c:0x8f94 / 0x103c:0x8f95 models but were left on
ALC245_FIXUP_HP_TAS2781_I2C_MUTE_LED, which drives the speaker mute
LED backwards: off when muted and on when unmuted.

Reassign these SSIDs to ALC245_FIXUP_HP_TAS2781_I2C_MUTE_LED_INVERTED
so the LED follows mute state correctly.

Fixes: 9afbbf490322 ("ALSA: hda/realtek - Enable Mute LED and Tas2781 for HP platform")
