From: Kailang Yang <kailang@realtek.com>

commit f86de9b1c0663b0a3ca2dcddec9aa910ff0fbf2c upstream.

Cannot adjust speaker's volume on Lenovo C940.
Applying the alc298_fixup_speaker_volume function can fix the issue.

[ Additional note: C940 has I2S amp for the speaker and this needs the
same initialization as Dell machines.
The patch was slightly modified so that the quirk entry is moved
next to the corresponding Dell quirk entry. -- tiwai ]
