This change wipes out a hardcoded macro, which enables codec bias level control. Now is_powered_on_standby value shall be used instead.

ALSA SOC usually puts the device in standby mode when it's not used
|
|
for sometime. If you unset is_powered_on_standby the driver will
|
|
turn off the ADC/DAC when this callback is invoked and turn it back
|
|
on when needed. Unfortunately this will result in a very light bump
|
|
(it can be audible only with good earphones). If this bothers you
|
|
set is_powered_on_standby, you will have slightly higher power
|
|
consumption. Please note that sending the L3 command for ADC is
|
|
enough to make the bump, so it doesn't make difference if you
|
|
completely take off power from the codec.
