media: drop CONFIG_MEDIA_CONTROLLER_REQUEST_API

2023-11-23T12:03:45Z

This config option was added during the development of the Request API to make it easy to disable it. The Request API is now stable so it is time to drop this option altogether. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: mc-device: remove unnecessary __must_check

2023-04-11T16:54:01Z

In the file mc-device.c, the function media_device_register_entity_notify() does not need to have the __must_check attribute since it returns only a value of 0. Therefore, we can remove this attribute and change the function's return type. Signed-off-by: Jason Kim Signed-off-by: Sakari Ailus Signed-off-by: Hans Verkuil

media: mc: Set bus_info in media_device_init()

2022-04-24T07:05:53Z

Set bus_info field based on struct device in media_device_init() and remove corresponding code from drivers. Also update media_device_init() documentation: the dev field must be now initialised before calling it. Signed-off-by: Sakari Ailus Reviewed-by: Laurent Pinchart Signed-off-by: Mauro Carvalho Chehab

media: mc: Remove redundant documentation

2022-04-24T07:01:38Z

media: mc-device.c: use DEVICE_ATTR_RO() helper macro

2021-08-04T12:43:50Z

Use DEVICE_ATTR_RO() helper macro instead of DEVICE_ATTR(), which is simpler and more readable. Due to the name of the read function of the sysfs attribute is normalized, there is a natural association. Signed-off-by: Zhen Lei Signed-off-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab

media: mc-device.c: change media_device_request_alloc to match media_ioctl_info

2020-08-29T06:15:23Z

We modified the type of media_device_request_alloc()'s second parameter from int* to void* so that it can match the interface defined in struct media_ioctl_info.
