Program tuner before demodulator in case of channel set. Earlier it was programmed during demodulator programming. This seems to resolve weird error where demodulator misses sometimes ability to gain lock. Signed-off-by:

This function has sanity checks to make sure that "dev" is non-null. I moved the dereference down below the checks. In the current code "dev" is never actually null. Signed-off-by:

Add a mutex_unlock missing on the error paths. The use of the mutex is balanced elsewhere in the file. The semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression E1; @@ * mutex_lock(E1,...); <+... when != E1 if (...) { ... when != E1 * return ...; } ...+> * mutex_unlock(E1,...); // </smpl> Signed-off-by:

Stanse found that in ivtvfb_callback_cleanup and ivtvfb_callback_init there are unneeded tests for itv being NULL. But itv is initialized as container_of with non-zero offset in those functions, so it is never NULL (even if v4l2_dev is). This was found because itv is dereferenced earlier than the test.

The lirc userspace needs all the current ioctls defined, and we need to put the header files in places out-of-tree and/or staging lirc drivers (which I plan to prep soon) can easily build with. I've actually tested this in a tree w/all the lirc drivers queued up to be submitted for staging. I'm also reasonably sure that Andy Walls is going to need most of the ioctls anyway for his cx23888 IR driver work. Signed-off-by:

This patch fixes possible race conditions in queue management with SMP: when a frame was completed, the irq function tried to use the next frame buffer. At this time, it was possible that the application on an other processor updated the frame pointer, making the image to point to a bad buffer. The patch contains two main changes: - the image transfer uses the queue indexes which are protected against simultaneous memory access, - the image pointer which is used for image concatenation is only set at interrupt level. Some subdrivers which used the image pointer have been updated. Reported-by:

The problem may occur with SMP: - a frame is completed at interrupt level (in gspca_frame_add with packet_type == LAST_PACKET, - just after clearing the bit V4L2_BUF_FLAG_QUEUED and before setting the bit V4L2_BUF_FLAG_DONE, on the other processor, the application tries to requeue the same frame buffer, - then, the qbuf function succeeds because ALL_FLAGS are not set. The fix sets and resets the two flags in one instruction. Reported-by:

As pointed by Christoph Egger <siccegge@stud.informatik.uni-erlangen.de>, The config Option DVB_DIBCOM_DEBUG was dropped while removing the dibusb driver in favor of dvb-usb in 2005. However it remaind existant at some places of the kernel config. Instead of just removing the debug capability, the better is to just remove the bad dependency, making the modprobe function always visible.

This patch to the si470x_vidioc_s_tuner function was developed in cooperation with Roel Kluin <roel.kluin@gmail.com>. It sets the default retval to 0 instead of -EINVAL, identical to what is done in all other set/get functions of v4l2_ioctl_ops. This is just as cosmetic change, as retval is directly overwritten by the si470x_disconnect_check() anyway. Signed-off-by:

Spent a while last night getting device initialization packet captures under Windows for all generations of devices. There are a few places where we were doing things differently, and few things we were doing that we don't need to do, particularly on gen3 hardware, and I *think* one of those things is what was locking up my pinnacle hw from time to time -- at least, its been perfectly well behaved every time its been plugged in since making this change. First up, we're adding a bit more to the gen1 init routine here. Its not absolutely necessary, the hardware works the same both with and without it, but I'd like to be consistent w/Windows here. Second, DEVICE_RESET is never called when initializing either of my gen3 devices, its only called for gen1 and gen2. The bits in the gen3 init after removing that, are safe (and interesting) to run on all hardware, so there's no more gen3-specific init done, there's instead a generic mceusb_get_parameters() that is run for all hardware. Third, the gen3 flag isn't needed. We only care if hardware is gen3 during probe, so I've dropped that from the device flags struct. Successfully tested on all three generations of mceusb hardware.

This should do the trick. Completely untested beyond compiling, but its not exactly a complicated fix, and in practice, I'm not aware of anyone ever actually tripping that locking bug, so there's zero functional change in typical use here.

Since commit b4028437 the 'driver_data' field resides in device's struct device_private which may be allocated by dev_set_drvdata() if device_private struct was not allocated previously. dev_set_drvdata() is used in video_set_drvdata() to set the driver's private data pointer in v4l2 drivers. Setting the private data _before_ registering the v4l2 device results in a memory leak since __video_register_device() also calls video_set_drvdata(), but after zeroing the device structure. Thus, the reference to the previously allocated device_private struct goes lost and a new device_private will be allocated. All v4l drivers which call video_set_drvdata() _before_ calling video_register_device() are affected. The patch fixes __video_register_device() to preserve previously allocated device_private reference. Caught by kmemleak. Signed-off-by:
