There is a new PCIe bridge chip(from SMI) used in DVBSky V3 seris cards, include S950 V3 and S952 V3 cards.
SMI pcie bridge chip is PCIe 1.1 compliant, supports MSI feature.
Main interface blocks:
1>Two DVB transport stream input ports(ts0,ts1).
2>Two I2C master bus(i2c0, i2c1).
3>IR controller.
4>reset pins and other GPIOs.
DVBSky S950 V3 card has a single channel of dvb-s/s2.
1>Frontend: tuner: M88TS2022, demod: M88DS3103
2>PCIe bridge: SMI PCIe

We can add two returns in the "if (state->srate >=

There is another "if (!lock) {" check which can be removed since we have
already checked "lock" and know it is zero at this point. This second

[media] cx88: convert to vb2
As usual, this patch is very large due to the fact that half a vb2 conversion
isn't possible. And since this affects blackbird, alsa, core, dvb, vbi and
video the changes are all over.
What made this more difficult was the peculiar way the risc program was setup.
The driver allowed for running out of buffers in which case the DMA would stop
and restart when the next buffer was queued. There was also a complicated
timeout system for when buffers weren't filled. This was replaced by a much
simpler scheme where there is always one buffer around and the DMA will just
cycle that buffer until a new buffer is queued. In that case the previous
buffer will be chained to the new buffer. An interrupt is generated at the
start of the new buffer telling the driver that the previous buffer can be
passed on to userspace.
Much simpler and more robust.

[media] af9005: fix kernel panic on init if compiled without IR
This patches fixes an ancient bug in the dvb_usb_af9005 driver, which
has been reported at least in the following threads:
https://lkml.org/lkml/2009/2/4/350
https://lkml.org/lkml/2014/9/18/558
If the driver is compiled in without any IR support (neither
DVB_USB_AF9005_REMOTE nor custom symbols), the symbol_request calls in
af9005_usb_module_init() return pointers != NULL although the IR
symbols are not available.
This leads to the following oops:

The prefered fix would be to convert the whole IR code to use the kernel IR
infrastructure (which wasn't available at the time this driver had been created).
Until anyone who still has this old hardware steps up an does the conversion,
fix it by not calling the symbol_request calls if the driver is compiled in
without the default IR symbols (CONFIG_DVB_USB_AF9005_REMOTE).
Due to the IR related pointers beeing NULL by default, IR support will then be disabled.
The downside of this solution is, that it will no longer be possible to
compile custom IR symbols (not using CONFIG_DVB_USB_AF9005_REMOTE) in.
Please note that this patch has NOT been tested with all possible cases.
I don't have the hardware and could only verify that it fixes the reported
bug.

0fb220f2a5cb. What happened is
that the conversion of debug messages to use pr_debug() was a
bad idea, because one needing to debug would need to both
enable debug level via a modprobe parameter, and then to
enable the dynamic printk's.
So, for now, let's use printk() directly at dprintk().
