Move the kzalloc and associated test after the stream/query test, to avoid the need to free the allocated if the stream/query test fails. The semantic match that finds the problem is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @r exists@ local idexpression x; statement S; expression E; identifier f,f1,l; position p1,p2; expression *ptr != NULL; @@ x@p1 = \(kmalloc\|kzalloc\|kcalloc\)(...); ... if (x == NULL) S <... when != x when != if (...) { <+...x...+> } ( x->f1 = E | (x->f1 == NULL || ...) | f(...,x->f1,...) ) ...> ( return \(0\|<+...x...+>\|ptr\); | return@p2 ...; ) @script:python@ p1 << r.p1; p2 << r.p2; @@ print "* file: %s kmalloc %s return %s" % (p1[0].file,p1[0].line,p2[0].line) // </smpl> Signed-off-by:

Due to rounding and clipping, exposure and gain settings do not map to unique register values. Rather than read the registers and report gain and exposure that may be different than the values that were set, just cache the latest values that were set and report them. Reduce exposure range from 0-65535 to 0-255 so libv4l's autogain doesn't take forever. Remove vestiges of driver signal processing that is now handled by libv4l. Signed-off-by:

http://linuxtv.org/wiki/index.php/Zolid_Hybrid_TV_Tuner test status analog (PAL-B): - Sometimes picture is noisy, but it becomes crystal clear after switching between channels. (happens for example at 687.25 Mhz) - On a lower frequency (511.25 Mhz) the picture is always sharp, but lacks colour. - No sound problems. - radio untested. Digital: - DVB-T/H stream reception works. - Would expect to see some more channels in the higher frequency region. Overall is the impression that sensitivity still needs improvement both in analog and digital modes. Signed-off-by:

When fast push-pull button of remote control we can received incorrect key code 0x00. Key information from IR decoder has ID of remote control 2 bytes, byte of key code and byte of mirror key code. Correct data 0x86 0x6B 0x00 0xFF Wrong data 0x86 0x6B 0x00 0x00 This patch added additional test of mirror byte for filtering. Signed-off-by:

This patch adds driver for 774 Friio White, ISDB-T USB receiver Friio White is an USB 2.0 ISDB-T receiver. (http://www.friio.com/) The device has a GL861 chip and a Comtech JDVBT90502 canned tuner module. This driver ignores all the frontend_parameters except frequency, as ISDB-T shares the same parameter configuration across the country and thus the device can work like an intelligent one. As this device does not include a CAM nor hardware descrambling feature, the driver passes through scrambled TS streams. There is Friio Black, a variant for ISDB-S, which shares the same USB Vendor/Product ID with White, but it is not supported in this driver. They should be identified in the initialization sequence, but this feature is not tested. Signed-off-by:

Add a driver for Earthsoft PT1 Eearthsoft PT1 is a PCI card for Japanese broadcasting with two ISDB-S and ISDB-T demodulators. This card has neither MPEG decoder nor conditional access module onboard. It transmits only compressed and possibly encrypted MPEG data over the PCI bus, so you need an external software decoder and a decrypter to watch TV on your computer. This driver is originally developed by Tomoaki Ishikawa <tomy@users.sourceforge.jp> by reverse engineering.

In ISDB-S, time-devision duplex is used to multiplexing several waves in the same frequency. Each wave is identified by its own transport stream ID, or TS ID. We need to provide some way to specify this ID from user applications to handle ISDB-S frontends. This code has been tested with the Earthsoft PT1 driver.

Following changes done for vpif driver to support vpif capture:- 1) Current version of display driver defined vpif register space as part for vpif display platform driver resource This is not correct since vpif is common across capture and display drivers. So the resource iomap function is moved to this module 2) Since there are common registers, a spinlock is added for mutual exclusion. This has incorporated comments against version v0 of the patch series Resending to merge to V4L linux-next Reviewed-by:

This is the vpif capture bridge driver for DM6467. This video supports two video channels each having a tvp5147 device at the input. This allows simultaneous capture of NTSC/PAL video in each of this channel. Both MMAP and USERPTR io mechanism are supported. Currently buffer allocation happens at REQBUF ioctl request. Since USERPTR IO is supported, this is not an issue since user applications can allocate buffers and pass the user space address to the driver. Following are TODOs :- 1) Adding support for allocation of buffers at init 2) VBI/HBI data service This has incorporated comments received against version v0 of the patch series.

The structure name for vpif display driver changed since it was not unique. So this update is done to reflect the same. Also removed the code related to register address space iomap. Uses v4l2_i2c_new_subdev_board() instead of v4l2_i2c_new_probed_subdev() so that platform data can be added for subdevice configuration for polarities. This has incorporated comments against version v0 of the patch series. Resending the original patch for merge to V4L linux-next Reviewed-by:

The term 'kernel number' is very vague, so replace it with the somewhat more descriptive term 'device node number'. In one place the local variable 'nr' was used to create the device node number of the new device name. This has been replaced with the vdev->num field to more clearly mark this as being the device node number and not the minor number. Signed-off-by:

The initial soc-camera scaling and cropping implementation turned out to be incompliant with the V4L2 API, e.g., it expected the user to specify cropping in output window pixels, instead of input window pixels. This patch converts the soc-camera core and all drivers to comply with the standard. Signed-off-by:

Use host-side image scaling when the client fails to set the requested format. We also have to take scaling into account when performing host-side cropping. Similar to cropping we try to use client-side scaling as much as possible to preserve bus bandwidth and optimise the frame-rate. Signed-off-by:

Prohibit S_FMT and S_CROP with a different window width or height after video buffer initialisation. This simplifies the work to be done in specific host and client drivers, and it doesn't seem to make much sense to allow these changes. We do however allow S_CROP with equal width and height to just move the window, this doesn't affect video buffer management and is usually easy enough to implement. Signed-off-by:
