The last set of drivers still using the parent field of video_device instead of the v4l2_dev field have been converted, so v4l2_dev is now always set. A proper pointer to v4l2_dev is necessary these days otherwise the advanced debugging ioctls will not work when addressing sub-devices. It also ensures that the core can always go from a video_device struct to the top-level v4l2_device struct. There is still one single use case for the parent pointer: if there are multiple busses, each being the parent of one or more video nodes, and if they all share the same v4l2_device struct. In that case one still needs a parent pointer since the v4l2_device struct can only refer to a single parent device. The cx88 driver is one such case. Unfortunately, the cx88 failed to set the parent pointer since 3.6. The next patch will correct this. In order to support this use-case the parent pointer is only renamed to dev_parent, not removed altogether. It has been renamed to ensure that the compiler will catch any (possibly out-of-tree) drivers that were missed during the conversion. Signed-off-by:

This driver did not yet support struct v4l2_device, so add it. This make it possible to replace the deprecated parent field with the v4l2_dev field, allowing the eventual removal of the parent field. Signed-off-by:

The parent field will eventually disappear to be replaced by v4l2_dev. soc_camera does provide a v4l2_device struct but did not point to it in struct video_device. This is now fixed. Now the video nodes can be found under the correct platform bus, and the advanced debug ioctls work correctly as well (the core implementation of those ioctls requires that v4l2_dev is set correctly).

It was possible to unregister an already unregistered v4l2_device struct. Add a check whether that already happened and just return if that was the case. Also refuse to register a v4l2_device if both the dev and name fields are empty. A warning was already produced in that case, but since the name field is now used to detect whether or not the v4l2_device was already unregistered this particular combination should be rejected.

Remove g_chip_ident from cx88. Also remove the v4l2-chip-ident.h include. The board code used defines from v4l2-chip-ident.h to tell the driver which audio chip is used. Replace this with a cx88-specific enum. Signed-off-by:

In dvb_ringbuffer lock-less synchronizationof reader and writer threads is done with separateread and write pointers. Sincedvb_ringbuffer_flush() modifies the read pointer, this function must not be called from the writer thread. This patch removes the dvb_ringbuffer_flush() calls in the dmxdev ringbuffer write functions, this fixes Oopses "Unable to handle kernel paging request" I could observe for the call chaindvb_demux_read ->dvb_dmxdev_buffer_read -> dvb_ringbuffer_read_user -> __copy_to_user (the reader side of the ringbuffer). The flush calls at the write side are not necessary anyway since ringbuffer_flush is also called in dvb_dmxdev_buffer_read() when an error condition is set in the ringbuffer. This patch should also be applied to stable kernels. Signed-off-by:

The GPIO register caching is the result of wrong assumptions and incomplete knowledge about the GPIO registers and their functionality. Today, we know that it is not needed. It is also limited to a single register and therefore incomplete (newer chips are using multiple registers). Instead of extending the caching, get rid of it, because it has no real benefits and just bloats/complicates the code. Signed-off-by:

The r820t_imr() calibration function of the Rafael Micro R820T tuner generates this error at every tune attempt: r820t 0-001a: No valid PLL values for 2252021 kHz! The function was inspired by the original Realtek driver for rtl2832 devices with the r820t tuner; anyway, in the original code the XTAL frequency of the tuner was expressed in KHz, while in the kernel driver it is expressed in Hz; so the calibration failed because of an out-of-range initial value. The final result of the computation is then passed to the r820t_set_mux() and r820t_set_pll() functions, but the conversion from KHz to Hz is already correctly implemented. Signed-off-by:

Remove all links of the subdev's media entity after internal_ops 'unregistered' call and right before unregistering the entity from a media device. It is assumed here that an unregistered (orphan) media entity cannot have links to other entities registered to a media device. It is also assumed the media links should be created/removed with the media graph's mutex held. The above implies that the caller of v4l2_device_unregister_subdev() must not hold the graph's mutex.

This function allows to remove all media entity's links to other entities, leaving no references to a media entity's links array at its remote entities. Currently, when a driver of some entity is removed it will free its media entities links[] array, leaving dangling pointers at other entities that are part of same media graph. This is troublesome when drivers of a media device entities are in separate kernel modules, removing only some modules will leave others in an incorrect state. This function is intended to be used when an entity is being unregistered from a media device. With an assumption that normally the media links should be created between media entities registered to a media device, with the graph mutex held. Signed-off-by:
