| Subject: [PATCH 1/4] BACKPORT: media: uapi/linux/media.h: add request API |
| |
| Define the public request API. |
| |
| This adds the new MEDIA_IOC_REQUEST_ALLOC ioctl to allocate a request |
| and two ioctls that operate on a request in order to queue the |
| contents of the request to the driver and to re-initialize the |
| request. |
