V4L/DVB (6210): pvrusb2: Do a far better job at setting the default initial video standard
The v4l tveeprom logic tells us what video standards are supported by
the hardware, however it doesn't directly tell us what should be the
preferred initial standard. For example "NTSC/NTSC-J" devices are
reported by tveeprom as support NTSC-M and PAL-M, and while that might
be true, in the vast majority of cases NTSC-M is really what the user
is going to want. However the driver previously just arbitrarily
picked the "lowest numbered" standard as the initial default, which in
that case would have been PAL-M. (And making matters more confusing -
this only caused real problems on 24xxx devices because the saa7115 on
29xxx seems to autodetect the right answer anyway.) This change
implements an algorithm that uses the set of "supported" standards as
a hint to decide on the initial standard. This algorithm ONLY comes
into play if the driver isn't specifically told what to do; said
another way - the user can always still change the standard via the
sysfs interface, via the usual V4L methods, or even specified as a
module parameter. The idea here is only to pick a better starting
point if the user (or app) doesn't otherwise do something to set the
standard; otherwise this change has no real impact.

the other channel only has a range of 0 to -63 dB. ALSA volume controls don't

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
