Use the balance control to make the mono volume control stereo.
Note that full range isn't supported. The balance control attenuates one
channel by 0 to -63 dB, and the volume control provides additional attenuation
to both channels by another 0 to -63 dB.
So the channel with the most attenuation has a range of 0 to -126 dB, while
the other channel only has a range of 0 to -63 dB. ALSA volume controls don't
appear to support this concept. I just limited the range to 0 to -63 total.
Once you get to -63 dB, you're already at silence, so additional attenuation
is pretty much pointless anyway.

To ease the conversion of the analog tuner sub-drivers into dvb_frontend
style tuner modules, we must remove the i2c_client interface.
dvb_frontend style tuner modules use i2c_transfer directly on the i2c_adapter.
This change only alters the interface between tuner.ko and the tuner
sub-drivers. The v4l2 / i2c_client interface to tuner.ko remains intact.
This patch adds inline functions tuner_i2c_xfer_send, and tuner_i2c_xfer_recv,
to replace i2c_master_send and i2c_master_recv inside the tuner sub-drivers.

The tuner module has a rather aggressive range of possible i2c addresses.
As per the specs available, it appears as if there are no 4-byte tuners that
actually use i2c addresses in the range 0x64 thru 0x6f, yet, tuner-core claims
the address range 0x60 thru 0x6f.
Allowing tuner.ko to probe these addresses can cause potential damage to
certain IR receivers, RTC chips or any other IC's that might otherwise reside
on the i2c bus using one of these addresses.
The plan is to remove these i2c addresses from the i2c address range of the
tuner module. If any devices are discovered that actually do have tuners at
one of these addresses, the newer i2c probing methods will be used to handle
those cases.
In order to collect this information and avoid any potential regressions,
the following warning has been added upon successful detection of a tuner
using an i2c address in the range 0x64 thru 0x6f:
====================== WARNING! ======================
Support for tuners in i2c address range 0x64 thru 0x6f
will soon be dropped. This message indicates that your
hardware has a {tuner name} tuner at i2c address {addr}.
To ensure continued support for your device, please
send a copy of this message, along with full dmesg
output to v4l-dvb-maintainer@linuxtv.org
Please use subject line: "obsolete tuner i2c address."
