2019-07-23media: ti-vpe: fix leaked of_node referencesWen Yang1-0/+1
The call to of_get_parent returns a node pointer with refcount incremented thus it must be explicitly decremented after the last usage. Detected by coccinelle with the following warnings: drivers/media/platform/ti-vpe/cal.c:1621:1-7: ERROR: missing of_node_put; acquired a node pointer with refcount incremented on line 1607, but without a corresponding object release within this function.

2018-10-04media: platform: Switch to v4l2_async_notifier_add_subdevSteve Longerbeam1-4/+29
Switch all media platform drivers to call v4l2_async_notifier_add_subdev() to add asd's to a notifier, in place of referencing the notifier->subdevs[] array. These drivers also must now call v4l2_async_notifier_init() before adding asd's to their notifiers. There may still be cases where a platform driver maintains a list of asd's that is a duplicate of the notifier asd_list, in which case its possible the platform driver list can be removed, and can reference the notifier asd_list instead. One example of where a duplicate list has been removed in this patch is xilinx-vipp.c. If there are such cases remaining, those drivers should be optimized to remove the duplicate platform driver asd lists. None of the changes to the platform drivers in this patch have been tested. Verify that the async subdevices needed by the platform are bound at load time, and that the driver unloads and reloads correctly with no memory leaking of asd objects.

2017-12-29media: v4l2-async: simplify v4l2_async_subdev structureMauro Carvalho Chehab1-1/+1
The V4L2_ASYNC_MATCH_FWNODE match criteria requires just one struct to be filled (struct fwnode_handle). The V4L2_ASYNC_MATCH_DEVNAME match criteria requires just a device name. So, it doesn't make sense to enclose those into structs, as the criteria can go directly into the union. That makes easier to document it, as we don't need to document weird senseless structs. At drivers, this makes even clearer about the match criteria.

2017-10-31media: v4l: async: Move async subdev notifier operations to a separate structureLaurent Pinchart1-2/+6
The async subdev notifier .bound(), .unbind() and .complete() operations are function pointers stored directly in the v4l2_async_subdev structure. As the structure isn't immutable, this creates a potential security risk as the function pointers are mutable. To fix this, move the function pointers to a new v4l2_async_subdev_operations structure that can be made const in drivers.
