If, in em28xx_usb_probe() the memory allocation
dev->alt_max_pkt_size = kmalloc(32*
dev->num_alt,GFP_KERNEL);
fails, then we'll bail out and return -ENOMEM.
The problem is that in that case we don't free the storage allocated
to 'dev', thus causing a memory leak.
This patch fixes the leak by freeing 'dev' before we return -ENOMEM.
This fixes Coverity bug #647.

Since videobuf_waiton is called with intr=1, it can return -EINTR and therefore
err may be non-zero. This happens when the system goes into the standby state.
Without the BUG() occurring, there's no problem with standby mode while DVB
is being used.

From: Hartmut Birr <e9hack@googlemail.com>
The min frequencies of the DVB-C frontends are wrong. In Europe, the center frequency of the lowest
channel is 50.5MHz and not 51MHz. All known cards with the stv0297/tda0002x/ves1820 frontend are
able to tune to this frequency. I've changed the range to the lowest channel - 1/2 bandwidth and the
highest channel + 1/2 bandwidth. For the design of the dvb driver, the frequency ranges must be part
of the tuner and not of the frontend itself. The same frontend may be used for different tuners. The
attached patch does only fix the ranges and not the design.

From: Hans Verkuil <hverkuil@xs4all.nl>
Audio muting for the tuner input was implemented by stopping the audio
microcontroller and restarting it on unmute. However, it appears that this
method can actually crash the audio firmware. It's rare and seems to
happen with NTSC only.
It has been reimplemented by setting to volume to 0. In addition, the
reporting of the mute state has been improved as well: it used to be
impossible to detect whether the audio was muted by the user or if it
was muted due to the microcontroller trying to detect the audio
standard. This is now clearly stated.

- Allow Xceive cards to be used without Xceive support
- Update Xceive support to latest userspace tuner (still not on by default,
pending inclusion of userspace tuner in the kernel).
- Use CONFIG_XC3028 rather than HAVE_XC3028: gentree.pl will remove them
automatically.

Add radio support for the Thomson DTT7612 tuner.
This tuner uses a different 1st intermediate frequency than the other radio
tuners supported (a lot of NTSC radio tuners probably need this change too).
Add a new tuner-simple parameter, radio_if. It selects the 1st IF used for
radio reception. The radio frequency setting code in tuner-simple now uses
this field, instead of a special case select() block for each tuner with radio
support.
The tuner parameters for tuners that used a 33.3 MHz RIF now set radio_if to 1
in tuner-types.c.
The Thomson DTT7612 gets radio_if = 2, also add has_tda9887 = 1 and
fm_gain_normal = 1.
Add some defines for tda9887 bits that control IF setting in radio mode.
Add a new tda9887 config option, TDA9887_RIF_41_3, that selects a 41.3 MHz
radio IF.
Fix the way tda9887 radio options work. The driver was modifying the default
radio mode config templates based on the TDA9887_XXXX flags. This means that
_all_ tuners would get the same settings. If you had a one tuner than used
TDA9887_GAIN_NORMAL and one that didn't, both would get the setting. Now the
tda9987 driver just checks if tuner mode is radio and then applies the config
settings directly to the data being sent, just like how all the TV mode
settings already work.
The PLL setting math is made a little more accurate.
And a grammar error in a printk is fixed.

In the current driver, the field order is global. As soon as it's changed it
takes immediate effect. This is a problem when the video changes order mid
stream. Although it mostly works okay, the video may judder / flicker.
This patch attaches the field order to the frame, so that any buffered frames
will not be displayed until the correct field. In the event that the field
order is changed mid stream, the driver will ensure that the previous frame
is displayed for a minimum of 3 fields. These are the two original fields the
frame should have occupied, plus the one extra since the new frame still has
to wait for the correct field.

The yuv output code always compares the new frame position & size with those
of the previous frame. If they are different, a flag is set to request the
yuv output registers be updated when the new frame is displayed.
If the incoming frames are delivered too fast, exhausting the buffers, the
most recent frame already buffered will be discarded. Unfortunately, any
update request will also be discarded. If the new frame matches the size &
position of the now discarded frame, the yuv registers are not flagged for
update & will remain in their old state.
This patch preserves the register update flag in the event that a frame is
dropped.

From: Ian Armstrong <ian@iarmst.demon.co.uk>
When the video standard is changed, there's no guarantee the framebuffer
dimensions are still legal. The yuv output code uses these dimensions to
calculate the size & position for the video overlay. If the framebuffer
dimensions are now illegal, the output may exceed the vertical limit of the
display, causing distortion.
This patch adds an additional check to ensure the output doesn't exceed
the limits for the current video standard, cropping if required.

After some tedious work with a logic probe and a magnifying glass, I've
determined that GPIO 7 is used to switch between the DTT7612's Sound 4.5 MHz
IF output on pin 12 and the FM 10.7MHz If output on pin 11. GPIO 2 is used to
switch the card's analog sound output from from the analog input connector to
the CX23883's audio DACs.
So, in radio mode GPIO2 = 1 and GPIO7 = 0.
Add some comments about how the HD-3000's GPIOs are connected.
Delete the vmux setting for the radio, as vmux doesn't apply to radio mode.
Also delete the lines setting unused gpio words to zero; it's not necessary as
0 is the default value for uninitialized fields.
