fe->tuner_priv and fe->ops.tuner_ops are initialized twice in r820t_attach(). Remove the redundant initializations and also move fe->ops.tuner_ops initialization outside of the mutex lock (as in the xc4000 tuner code for example). 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:

Error handling of usb_submit_urb() is not as all others in imon_probe(). It just unlocks mutexes and returns nonzero leaving all already allocated resources unfreed. The patch makes sure all the resources are deallocated. Found by Linux Driver Verification project (linuxtesting.org). 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: -

The sensor is powered by three supplies. Use the bulk regulator API to enable and disable them instead of performing the operations manually. This fixes a warning caused by ignoring the return value of regulator_enable(). Signed-off-by:

Hans Verkuil authored
Currently, if the norm set is V4L2_STD_ALL, then autodetect the current standard and use that. This is non-standard behavior, and in fact it hasn't worked for a very long time: before s_std is called in this driver, the v4l2 core will mask it with the tvnorms field. So even if the application passes V4L2_STD_ALL, the zoran driver will always see a subset of that. Since nobody ever complained about this we just remove this non-standard functionality.

The use of current_norm to keep track of the current standard has been deprecated for quite some time. Now that all drivers that were using it have been converted to use g_std we can drop it from the core. It was a bad idea to introduce this at the time: since it is a per-device node field it didn't work for drivers that create multiple nodes, all sharing the same tuner (e.g. video and vbi nodes, or a raw video node and a compressed video node). In addition it was very surprising behavior that g_std was implemented in the core. Often drivers implemented both g_std and current_norm, because they didn't understand how it should be used. Since the benefits were very limited (if they were there at all), it is better to just drop it and require that drivers just implement g_std. Signed-off-by:
