ALSA: usb-audio: Fix dB level of Bose Revolve+ SoundLink
[ Upstream commit 02eb1d098e26f34c8f047b0b1cee6f4433a34bd1 ]
Bose Revolve+ SoundLink (0a57:40fa) advertises invalid dB level for
the speaker volume. This patch provides the correction in the mixer
map quirk table entry.
Note that this requires the prerequisite change to add min_mute flag
to the dB map table.
