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:

As USB/PCI/MEDIA_SUPPORT dependencies can be tristate, we can't simply make the bool menu to be dependent on it. Everything below the menu should also depend on it, otherwise, we risk to allow building them with 'y', while only 'm' would be supported. So, add an IF just before everything below, in order to avoid such risks. Signed-off-by: -
