Adds support for the Plextor ConvertX PX-AV100U, which uses the eMPIA EM2820 chip. The device has a device_id of '0x093b, 0xa003'. I am using the existing EM2820_BOARD_PINNACLE_DVC_90 board profile, as the Pinnacle Dazzle DVC 90/100/101/107, Kaiser Baas Video to DVD maker, and Kworld DVD Maker 2 were already mapped to it. Some more background on the device and my testing can be found at http://www.donkramer.net/plextor_122710.pdfSigned-off-by:

The VIDIOC_LOG_STATUS ioctl allows to dump the current status of a driver to the kernel log. Currently this ioctl is only available at video device nodes and the subdevs rely on the host driver to expose their core.log_status operation to user space. This patch adds VIDIOC_LOG_STATUS support at the sub-device nodes, for standalone subdevs that expose their own /dev entry. Acked-by:

The following ioctl sequence causes fimc_dma_run() to start processing without complete scaler and DMA initialization which causes missing interrupt and blocking on DQBUF: S_FMT, STREAMON, QBUF, DQBUF, STREAMOFF, STREAMON, QBUF, DQBUF. Fix this regression caused by moving pm_runtime* calls to start/stop_streaming callback by making sure the fimc_m2m_resume() is always invoked when expected. Reported-by:

It is not common for dvb_net_init to fail, but after the patch "dvb_net_init: return -errno on error" it can fail due to running out of memory. Handle this. From an audit of dvb_net_init callers. Signed-off-by:

Avoid some repetition by adopting the usual "goto err" idiom for error handling. Signed-off-by:
-
Jonathan Nieder authored
Repeating the same cleanup code in each error handling path makes life unnecessarily difficult for reviewers, who much check each instance of the same copy+pasted code separately. A "goto" to the end of the function is more maintainable and conveys the intent more clearly. While we're touching this code, also lift some assignments from "if" conditionals for simplicity. No functional change intended. Signed-off-by:

videobuf_dvb_register_bus relies on dvb_net_init to set dvbnet->dvbdev on success, but ever since commit fcc8e7d8 ("dvb_net: Simplify the code if DVB NET is not defined"), ->dvbdev is left unset when networking support is disabled. Therefore in such configurations videobuf_dvb_register_bus always returns failure, tripping little-tested error handling paths and preventing the device from being initialized and used. Now that dvb_net_init returns a nonzero value on error, we can use that as a more reliable error indication. Do so. Now your card be used with CONFIG_DVB_NET=n, and the kernel will pass on a more useful error code describing what happened when CONFIG_DVB_NET=y but dvb_net_init fails due to resource exhaustion.

dvb_net_init unconditionally returns 0. Callers such as videobuf_dvb_register_frontend examine dvbnet->dvbdev instead of the return value to tell whether the operation succeeded. If it has been set to a valid pointer, success; if it was left equal to NULL, failure. Alas, there is an edge case where that logic does not work as well: when network support has been compiled out (CONFIG_DVB_NET=n), we want dvb_net_init and related operations to behave as no-ops and always succeed, but there is no appropriate value to which to set dvb->dvbdev to indicate this. Let dvb_net_init return a meaningful error code, as preparation for adapting callers to look at that instead. The only immediate impact of this patch should be to make the few callers that already check for an error code from dvb_net_init behave a little more sensibly when it fails. Signed-off-by:

The function v4l2_device_register() is called too late in vpif_probe(). This meant that vpif_obj.v4l2_dev is accessed before it is initialized which caused a crash. This used to work in the past, but video_register_device() is now actually using the v4l2_dev pointer. Note that vpif_display.c doesn't have this bug, there v4l2_device_register() is called at the beginning of vpif_probe. Signed-off-by:

dw2102_properties et al refer to entries in the USB-id table using hard-coded indices, as in "&dw2102_table[6]", which means adding new entries before the end of the list has the potential to introduce bugs in code elsewhere in the file. Use C99-style initializers with symbolic names for each index to avoid this. This way, other device tables wanting to reuse the USB ids can use expressions like "&dw2102_table[TEVII_S630]" that do not change as the entries in the table are reordered. Signed-off-by:

The conditional after the kzalloc says that the tested expression should never be true, but if it were, the allocated data would have to be freed. This change just moves the allocation below the test, to avoid any possibility of the problem. A simplified version of the semantic match that finds the problem is as follows: (http://coccinelle.lip6.fr) // <smpl> @r exists@ local idexpression x; statement S; identifier f1; position p1,p2; expression *ptr != NULL; @@ x@p1 = \(kmalloc\|kzalloc\|kcalloc\)(...); ... if (x == NULL) S <... when != x when != if (...) { <+...x...+> } 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:

As our general practice, we use stream off before we close the video node. So that the drivers its stream off function would be called before its remove function. But for the case for ctrl+c, the program would be force closed. We have no chance to call that vb2 stream off from user space, but directly call the remove function in soc_camera. In that common code of soc_camera: ici->ops->remove(icd); if (ici->ops->init_videobuf2) vb2_queue_release(&icd->vb2_vidq); It would first call the device remove function, then release vb2, in which stream off function is called. Thus it create different order for the driver. This patch change the order to make driver see the same sequence to make it happy. Signed-off-by:Lei Wen <leiwen@marvell.com> Signed-off-by:

mt9m111 camera sensors support cropping and scaling. The current implementation is broken. For example, .s_crop() sets output frame sizes instead of the input cropping window. This patch adds a proper implementation of these methods. Besides it adds a sensor-disable and -enable operations on first open() and last close() respectively, to save power while closed and to return the camera to the default power-on state.

Before this patch the resulting values from a try_fmt were different then those from a s_fmt with the same parameters. try_fmt simply did not touch / fill some values like bytesperline at all. This patch also corrects bytesperline to the proper value for a planar format such as the YUV420P format the pwc driver produces, which is the bytesperline value for the biggest plane, rather then those of all planes added together.
