Subject: [RFC PATCH v8 0/4] Media Device Allocator API
Date: Thu, 1 Nov 2018 18:31:29 -0600 [thread overview]
Message-ID: <cover.1541118238.git.shuah@kernel.org> (raw)
From: Shuah Khan <shuah@kernel.org>
This patch series has been on the ice for the last couple of years.
Mauro asked me to restart the discussion on this and see if we can
make progress.
I rebased the series to Linux 4.19. It has been surprisingly well
preserved with one small merge conflict resolved in 0004.
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.
- No changes to 0001,0002 code since the v7 referenced below.
- 0003 is a new patch to enable ALSA defines that have been
disabled for kernel between 4.9 and 4.19.
- Minor merge conflict resolution in 0004.
- Added SPDX to new files.

Please review. I am sending this as RFC even though it has been tested
several times prior to this non-event rebased v8. I ran sanity tests.
