Subject: ASoC: tas2552: fix dBscale-min declaration
From: Andreas Dannenberg <[email protected]>
commit e2600460bc3aa14ca1df86318a327cbbabedf9a8 upstream.
The minimum volume level for the TAS2552 (control register value 0x00)
is -7dB however the driver declares it as -0.07dB.
Running amixer before the patch reports:
dBscale-min=-0.07dB,step=1.00dB,mute=0
Running amixer with the patch applied reports:
dBscale-min=-7.00dB,step=1.00dB,mute=0
