to fix the problem.

[media] media: fix au0828_analog_register() to not free au0828_dev
au0828_analog_register() frees au0828_dev when it fails to
locate isoc endpoint. au0828_usb_probe() continues with dvb
and rc probe and registration assuming dev is still valid.
When au0828_analog_register() fails to locate isoc endpoint,
it should return without free'ing au0828_dev. Otherwise, the
probe will fail as dev is null when au0828_dvb_register() is
called.

[media] adv7180: Add fast switch support
In fast switch mode the adv7180 (and similar) can lock onto a new signal
faster when switching between different inputs. As a downside though it is
no longer able to auto-detect the incoming format.
The fast switch mode is exposed as a boolean v4l control that allows
userspace applications to either enable or disable fast switch mode.

[media] adv7180: Add I2P support
Some of the devices supported by this driver have a interlaced-to-
progressive converter which can optionally be enabled. This patch adds
support for enabling and disabling the I2P converter on such devices.
I2P mode can be enabled by selecting V4L2_FIELD_NONE instead of
V4L2_FIELD_INTERLACED for the format.

This patch adds support for the adv7280-m/adv2781-m/adv7281-ma/adv7282-m
devices to the adv7180 driver. They are very similar to the
adv7280/adv7281/adv7282 but instead of parallel video out they feature a
MIPI CSI2 transmitter.
The CSI2 transmitter is configured via a separate I2C address, so we need to
register a dummy device for it.

[media] adv7180: Prepare for multi-chip support
The adv7180 is part of a larger family of device, which have all a very
similar register map layout. This patch prepares the adv7180 driver for
support for multiple different devices. For now the only difference we care
about is the number of input channel configurations. Also the way the input
format is configured slightly differs between some devices.
