media: v4l: async: Set v4l2_device and subdev in async notifier init

2023-08-10T05:58:32+00:00

Set the v4l2_device already in async notifier init, so struct device related to it will be available before the notifier is registered. This requires separating notifier initialisation into two functions, one that takes v4l2_device as its argument, v4l2_async_nf_init and v4l2_async_subdev_nf_init, for sub-device notifiers. Registering the notifier will use a single function, v4l2_async_nf_register. This is done in order to make struct device available earlier, during construction of the async connections, for sensible debug prints.

media: v4l: async: Rename v4l2_async_subdev as v4l2_async_connection

2023-07-28T08:44:25+00:00

Rename v4l2_async_subdev as v4l2_async_connection, in order to differentiate between the sub-devices and their connections: one sub-device can have many connections but the V4L2 async framework has so far allowed just a single one. Connections in this context will later translate into either MC ancillary or data links. This patch prepares changing that relation by changing existing users of v4l2_async_subdev to switch to v4l2_async_connection. Async sub-devices themselves will not be needed anymore Additionally, __v4l2_async_nf_add_subdev() has been renamed __v4l2_async_nf_add_connection().

media: Use designated initializers for all subdev pad ops

2023-04-12T07:46:07+00:00

Structures passed to subdev pad operations are all zero-initialized when declaring variables. In most cases, this is done with designated initializers to initialize some of the fields to specific values, but in a minority of cases the structures are zero-initialized by assigning them to '{ 0 }' or '{ }'. Improve coding style consistency by using designated initializers where possible, always initializing the 'which' field.

media: microchip-sama7g5-isc: Convert to platform remove callback returning void

2023-04-11T14:59:15+00:00

The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Trivially convert this driver from always returning zero in the remove callback to the void returning variant. Signed-off-by: Uwe Kleine-König Signed-off-by: Hans Verkuil
