If sanity check fails in scu_command(), goto error leads to unlock of an unheld mutex. The check should not fail in reality, but it nevertheless worth fixing. Found by Linux Driver Verification project (linuxtesting.org). Signed-off-by:

There are some softwares (Kaffeine and likely xine) that uses a DVBv5 call to switch to DVB-S2, but expects that a DVBv3 call to switch back to DVB-S. Well, this is not right, as a DVBv3 call doesn't know anything about delivery systems. However, as, by accident, this used to work, we need to restore its behavior, in order to avoid regressions with those softwares. Reported on this Fedora 16 bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=812895Reported-by:

The driver frees the clock samples buffer before stopping the video buffers queue. If a DQBUF call arrives in-between, uvc_video_clock_update() will be called with a NULL clock samples buffer, leading to a crash. This occurs very frequently when using the webcam with the flash browser plugin. Move clock initialization/cleanup to uvc_video_enable() in order to free the clock samples buffer after the queue is stopped. Make sure the clock is reset at resume time to avoid miscalculating timestamps. Signed-off-by:

No, this is the correct patch: RADIO_MAXIRADIO should be treated just like RADIO_SF16FMR2, I just didn't realize at the time that it had to be added as a SND_TEA575X dependency. Signed-off-by:

On some systems the device does not respond or give obscure values after cold, warm or firmware reboot. This patch retries to get chip version and type 5 times. If it fails it applies chip version 0x1 and type 0x9135. This patch does not fix warm cycle problems from other operating systems and indeed the reverse applies. Users should power off cold boot.

The commit e399ce77 has broken the DVB ABI for xine: The problem is that xine is expecting every event after a successful FE_SET_FRONTEND ioctl to have a non-zero frequency parameter, regardless of whether the tuning process has LOCKed yet. What used to happen is that the events inherited the initial tuning parameters from the FE_SET_FRONTEND call. However, the fepriv->parameters_out struct is now not initialised until the status contains the FE_HAS_LOCK bit. You might argue that this behaviour is intentional, except that if an application other than xine uses the DVB adapter and manages to set the parameters_out.frequency field to something other than zero, then xine no longer has any problems until either the adapter is replugged or the kernel modules reloaded. This can only mean that the fepriv->parameters_out struct still contains the (stale) tuning information from the previous application. Signed-off-by:

stb0899: fix the limits for signal strength values stb0899_read_signal_strength() adds an offset to the result of the table lookup. That offset must correspond to the lowest value in the lookup table, to make sure the result doesn't get below 0, which would mean a "very high" value since the parameter is unsigned. 'strength' and 'snr' need to be initialized to 0 to make sure they have a defined result in case there is no "internal->lock". Signed-off-by:

It is mostly copy/paste of the 520e code with setting GPIO7 removed (no LED light). I've worked on just released vanilla linux-3.3.0 kernel, so there may be 1/2 lines offset to the internal working source, but most of the code should apply cleanly. I was able to get the DVB-C working (tuned and watched TV). Haven't tested DVB-T (no signal atm). Special thanks to everybody who worked on the code and to Antti Palosaari and Devin Heitmueller who provided essential support on irc.

Hardware is based of: Empia EM2884 Micronas DRX 3926K NXP TDA18271HDC2 ... + analog parts. Analog is not supported currently. Only DVB-T and DVB-C. There seems to be still problems for locking DVB-C channels which have strong signal. Attenuator helps. I think it is demodulator IF/RF AGC issue. Lets fix it later. Patches are welcome.

I found one more place where -EINVAL is used instead of -ENOTTY: Note that drivers/media/dvb/dvb-core/dvbdev.c has the same code, but as far as I can tell DVB is still using -EINVAL for unknown ioctls so I didn't change that. Signed-off-by:

The D1F5 revision of the WinTV HVR-1900 uses a tda18271c2 tuner instead of a tda18271c1 tuner as used in revision D1E9. To account for this, we must hardcode the frontend configuration to use the same IF frequency configuration for both revisions of the device. 6MHz DVB-T is unaffected by this issue, as the recommended IF Frequency configuration for 6MHz DVB-T is the same on both c1 and c2 revisions of the tda18271 tuner.

We still need to power up the controller to avoid unsightly self-immolation should something try to access its registers, but the sensor can stay powered down unless the camera was actually operating at suspend time.

I had learned through hard experience that dinking around with the DMA descriptors while the C1_DESC_ENA enable bit was set is a recipe for all kinds of truly malicious behavior on the hardware's part, regardless of whether the DMA engine is actually operating at the time. That notwithstanding, the driver did so dink, resulting in "green frame" captures and the death of the system in random, spectacular ways. Move the tweaking of C1_DESC_ENA to the same function that sets the descriptor so we know that we'll never try to set a descriptor while that bit is set. Signed-off-by:

Experience shows that, on the Armada platform, it can take as much as 120ms for the DMA engine to actually shut down after it has been told to. So a 40ms timeout is not adequate; use 150ms instead. Also make sure we don't leave the DMA_ACTIVE flag set once things are down. Signed-off-by:

The marvell cam driver retained just enough of the owner-tracking logic from cafe_ccic to be broken; it could, conceivably, cause the driver to release DMA memory while the controller is still active.

The controller stop/restart logic could possibly restart DMA after the driver things things have stopped, with suitably ugly results. Make sure that we only restart the hardware if we're supposed to be streaming. Signed-off-by:
