media: sunxi: fix pm_runtime_get_sync() usage count

2021-07-14T14:59:16Z

[ Upstream commit 9c298f82d8392f799a0595f50076afa1d91e9092 ] The pm_runtime_get_sync() internally increments the dev->power.usage_count without decrementing it, even on errors. Replace it by the new pm_runtime_resume_and_get(), introduced by: commit dd8088d5a896 ("PM: runtime: Add pm_runtime_resume_and_get to deal with usage counter") in order to properly decrement the usage counter, avoiding a potential PM usage counter leak.

[ Upstream commit f3d384e36630e2a552d874e422835606d9cf230a ] When sun6i_video_remote_subdev() returns NULL to subdev, no error return code of sun6i_video_start_streaming() is assigned. To fix this bug, ret is assigned with -EINVAL in this case.

media: sun8i-di: Fix runtime PM imbalance in deinterlace_start_streaming

2021-05-12T06:39:50Z

[ Upstream commit f1995d5e43cf897f63b4d7a7f84a252d891ae820 ] pm_runtime_get_sync() will increase the runtime PM counter even it returns an error. Thus a pairing decrement is needed to prevent refcount leak. Fix this by replacing this API with pm_runtime_resume_and_get(), which will not change the runtime PM counter on error.

media: v4l2-async: Improve v4l2_async_notifier_add_*_subdev() API

2021-02-06T08:18:53Z

The functions that add an async subdev to an async subdev notifier take as an argument the size of the container structure they need to allocate. This is error prone, as passing an invalid size will not be caught by the compiler. Wrap those functions in macros that take a container type instead of a size, and cast the returned pointer to the desired type. The compiler will catch mistakes if the incorrect type is passed to the macro, as the assignment types won't match.

media: v4l2-async: Clean v4l2_async_notifier_add_fwnode_remote_subdev

2021-02-06T07:40:36Z

Change v4l2_async_notifier_add_fwnode_remote_subdev semantics so it allocates the struct v4l2_async_subdev pointer. This makes the API consistent: the v4l2-async subdevice addition functions have now a unified usage model. This model is simpler, as it makes v4l2-async responsible for the allocation and release of the subdevice descriptor, and no longer something the driver has to worry about. On the user side, the change makes the API simpler for the drivers to use and less error-prone.
