Subject: [PATCH v2 0/2] Media Device Allocator API
Date: Tue, 24 May 2016 17:39:46 -0600 [thread overview]
Message-ID: <cover.1464132578.git.shuahkh@osg.samsung.com> (raw)
Media Device Allocator API to allows multiple drivers share a media device.
Using this API, drivers can allocate a media device with the shared struct
device as the key. Once the media device is allocated by a driver, other
drivers can get a reference to it. The media device is released when all
the references are released.
This patch series has been tested with au0828 and snd-usb-audio drivers.
snd-us-audio patch isn't included in this series. Once this patch series
is reviews and gets a stable state, I will send out the snd-usb-audio
patch.
Changes since Patch v1 series: (based on Hans Virkuil's review)
- Removed media_device_get() and media_device_allocate(). These are
unnecessary.
- media_device_usb_allocate() holds media_device_lock to do allocate
and initialize the media device.
- Changed media_device_put() to media_device_delete() for symmetry with
media_device_*_allocate().
- Dropped media_device_unregister_put(). au0828 calls media_device_delete()
instead.
