* [media] v4l: Add VIDIOC_LOG_STATUS support for sub-device nodesSylwester Nawrocki2012-01-061-0/+4
| | | | | | | | | | | | | | | 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.

* [media] s5p-fimc: Prevent lock up caused by incomplete H/W initializationSylwester Nawrocki2012-01-061-3/+2
| | | | | | | | | | | | | | | 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.

* [media] videobuf-dvb: avoid spurious ENOMEM when CONFIG_DVB_NET=nJonathan Nieder2012-01-061-3/+4
| | | | | | | | | | | | | | | | | | | | | videobuf_dvb_register_bus relies on dvb_net_init to set dvbnet->dvbdev on success, but ever since commit fcc8e7d8c0e2 ("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.

* [media] DVB: dvb_net_init: return -errno on errorJonathan Nieder2012-01-061-3/+1
| | | | | | | | | | | | | | | | | | | | | | | | 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.

* [media] soc-camera: change order of removing deviceLei Wen2012-01-061-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
