While committing a change on em28xx, I got a warning of a typo there. So, fix it on em28xx and on two other media drivers with the same typo. Signed-off-by:Mauro Carvalho Chehab <mchehab@s-opensource.com>

There's a new version of Terratec H6 with uses USB ID 0ccd:10b2. This version is similar to the old one (with is supported via the HTC entry), except that this one has the eeprom on the second bus. On this board, one side of this board is labeled with: dvbc v2.0 The other side with: 94V-0, MO2, RK-4221 with huge digits: 1107 With those patches, the board is properly detected: em28xx 1-1.5:1.0: New device TERRATEC TERRATCE H5 MKII @ 480 Mbps (0ccd:10b2, interface 0, class 0) em28xx 1-1.5:1.0: Audio interface 0 found (Vendor Class) em28xx 1-1.5:1.0: Video interface 0 found: isoc em28xx 1-1.5:1.0: DVB interface 0 found: isoc em28xx 1-1.5:1.0: chip ID is em2884 em28xx eeprom 00000000: 26 00 00 00 02 0b 0f e5 f5 64 01 60 09 e5 f5 64 &........d.`...d em28xx eeprom 00000010: 09 60 03 c2 c6 22 e5 f7 b4 03 13 e5 f6 b4 87 03 .`...".......... em28xx eeprom 00000020: 02 0a b9 e5 f6 b4 93 03 02 09 46 c2 c6 22 c2 c6 ..........F..".. em28xx eeprom 00000030: 22 00 60 00 ef 70 08 85 3d 82 85 3c 83 93 ff ef ".`..p..=..<.... em28xx eeprom 00000040: 60 19 85 3d 82 85 3c 83 e4 93 12 07 a3 12 0a fe `..=..<......... em28xx eeprom 00000050: 05 3d e5 3d 70 02 05 3c 1f 80 e4 22 12 0b 06 02 .=.=p..<...".... em28xx eeprom 00000060: 07 e2 01 00 1a eb 67 95 cd 0c b2 10 f0 13 6b 03 ......g.......k. em28xx eeprom 00000070: 98 22 6a 1c 86 12 27 57 4e 16 29 00 60 00 00 00 ."j...'WN.).`... em28xx eeprom 00000080: 02 00 00 00 5e 00 13 00 f0 10 44 82 82 00 00 00 ....^.....D..... em28xx eeprom 00000090: 5b 81 c0 00 00 00 20 40 20 80 02 20 10 01 00 00 [..... @ .. .... em28xx eeprom 000000a0: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ em28xx eeprom 000000b0: c6 40 00 00 81 00 00 00 00 00 00 00 00 c4 00 00 .@.............. em28xx eeprom 000000c0: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 1c 03 ................ em28xx eeprom 000000d0: 31 00 32 00 33 00 34 00 35 00 36 00 37 00 38 00 1.2.3.4.5.6.7.8. em28xx eeprom 000000e0: 39 00 41 00 42 00 43 00 44 00 12 03 54 00 45 00 9.A.B.C.D...T.E. em28xx eeprom 000000f0: 52 00 52 00 41 00 54 00 45 00 43 00 22 03 54 00 R.R.A.T.E.C.".T. em28xx 1-1.5:1.0: eeprom 000100: ...

While testing support for Terratec H6 rev. 2, it was noticed that reading from eeprom there causes a timeout error. Apparently, this is due to the need of properly setting GPIOs. In any case, the driver doesn't really require eeprom reading to succeed, as this is currently used only for debug. So, Ignore such errors. Signed-off-by:

Mostly this adds some unlocks to error paths. But, if you see where there were "break;" statements before, I changed those paths to return error codes instead of returning success. Signed-off-by:

This patch mostly adds unlocks to error paths. But one additional small change is that I made the first "break;" a "goto unlock;" which means that now we return failure instead of success on that path. Signed-off-by:

Side effect: KERN_DEBUG messages aren't written to the kernel log anymore. This also improves the tda18212_ping reporting a bit so users know that if pinging wasn't successful, bad things will happen. Since in module_init_ddbridge() there's no dev yet, pr_info is used instead. Signed-off-by:

The current pre-decrement is incorrect and should be replaced with a post-decrement. Consider the case where the very first clk_prepare_enable fails when i is 0; in this case the error clean up will decrement the unsigned int which wraps to the largest unsigned int value causing an array out of bounds read on core->clks[i].

Back in April I created a patch to address a false-positive warning: drivers/media/usb/rainshadow-cec/rainshadow-cec.c: In function 'rain_irq_work_handler': drivers/media/usb/rainshadow-cec/rainshadow-cec.c:171:31: error: 'data' may be used uninitialized in this function [-Werror=maybe-uninitialized] My patch was totally wrong and introduced a real bug, and Colin Ian King thankfully noticed it now and fixed my mistake. Unfortunately, fixing the actual uninitialized data in this case brought back the original bogus warning. This is a new version of the patch, which simplifies the code to the point where gcc notices the behavior is correct.

Drivers must not perform unbalanced calls to stop the entity pipeline, however if they do they will fault in the core media code, as the entity->pipe will be set as NULL. We handle this gracefully in the core with a WARN for the developer. Replace the erroneous check on zero streaming counts, with a check on NULL pipe elements instead, as this is the symptom of unbalanced media_pipeline_stop calls. Signed-off-by:

Unfortunately the use of 'type' was inconsistent for multiplanar buffer types. Starting with 4.13 both the normal and _MPLANE variants are allowed, thus making it possible to write sensible code. Yes, we messed up :-( Signed-off-by:

The type field in struct v4l2_selection is supposed to never use the _MPLANE variants. E.g. if the driver supports V4L2_BUF_TYPE_VIDEO_CAPTURE_MPLANE, then userspace should still pass V4L2_BUF_TYPE_VIDEO_CAPTURE. The reasons for this are lost in the mists of time, but it is really annoying. In addition, the exynos drivers didn't follow this rule and instead expected the _MPLANE type. To fix that code is added to the v4l2 core that maps the _MPLANE buffer types to their regular equivalents before calling the driver. Effectively this allows for userspace to use either _MPLANE or the regular buffer type. This keeps backwards compatibility while making things easier for userspace. Since drivers now never see the _MPLANE buffer types the exynos drivers had to be adapted as well. Signed-off-by:

Change the core structure for adding subdevices in the topology. Instead of calling the specific create function for each subdevice, inject a child platform_device with the driver's name. Each type of node in the topology (sensor, capture, debayer, scaler) will register a platform_driver with the corresponding name through the component subsystem. Implementing a new subdevice type doesn't require vimc-core to be altered. This facilitates future implementation of dynamic entities, where hotpluging an entity in the topology is just a matter of registering/unregistering a platform_device in the system. It also facilitates other implementations of different nodes without touching the core code and remove the need of a header file for each type of node. Signed-off-by:

Commit e7890297 ("i2c: sh_mobile: don't send a stop condition by default inside transfers") makes the i2c_sh_mobile I2C-adapter emit a stop/start sequence between messages in a single transfer only when explicitly requested with I2C_M_STOP. This breaks the ov772x driver in the SH4 Migo-R board as the Omnivision sensor uses the I2C-like SCCB protocol that doesn't support repeated starts: i2c-sh_mobile i2c-sh_mobile.0: Transfer request timed out ov772x 0-0021: Product ID error 92:92 Fix it by marking the client as SCCB, forcing the emission of a stop/start sequence between all messages. As I2C_M_STOP requires the I2C adapter to support protocol mangling, ensure that the I2C_FUNC_PROTOCOL_MANGLING functionality is available. Tested on SH4 Migo-R board, with OV772x now successfully probing soc-camera-pdrv soc-camera-pdrv.0: Probing soc-camera-pdrv.0 ov772x 0-0021: ov7725 Product ID 77:21 Manufacturer ID 7f:a2 Signed-off-by:

'struct video_event' is used for the VIDEO_GET_EVENT ioctl, implemented by drivers/media/pci/ivtv/ivtv-ioctl.c and drivers/media/pci/ttpci/av7110_av.c. The structure contains a 'time_t', which will be redefined in the future to be 64-bit wide, causing an incompatible ABI change for this ioctl. As it turns out, neither of the drivers currently sets the timestamp field, and it is presumably useless anyway because of the limited resolutions (no sub-second times). This means we can simply change the structure definition to use a 'long' instead of 'time_t' and remain compatible with all existing user space binaries when time_t gets changed. If anybody ever starts using this field, they have to make sure not to use 1970 based seconds in there, as those overflow in 2038. Signed-off-by:
