Merge tag 'media/v6.3-1' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media
Pull media updates from Mauro Carvalho Chehab:
- Removal of several VB1-only deprecated drivers: cpia2, fsl-viu, meye,
stkwebcam, tm6000, vpfe_capture and zr364xx
- saa7146 recovered from staging/deprecated. We opted to give ti a
chance, and, instead of deprecating it, the intention is to write
patches migrating it from VB1 to VB2.
- av7110 returned from staging/deprecated/ to staging/ as we're not
planning on dropping it any time soon
- media controller API has gained experimental support for G_ROUTING
and streams API. No drivers use it right now. We're planning to add
one after -rc1, giving some time to experience the API and eventually
have changes during the next development cycle
- New sensor drivers: imx296, imx415, ov8858
- Atomisp had lots of changes, specially on its sensor's interface,
making atomisp sensor drivers closer to normal sensor drivers
- media controller kAPI has gained some helpers to traverse pipelines
- uvcvideo now better support power line control
- lots of bug fixes, cleanups and driver improvements

If no audio stream type is +set the id has to be in [0xC0,0xDF] for MPEG sound, in [0x80,0x87] for +AC3 and in [0xA0,0xA7] for LPCM. More specifications may follow for +other stream types. If the stream type is set the id just specifies the +substream id of the audio stream and only the first 5 bits are +recognized. + +Return Value +------------ + +On success 0 is returned, on error -1 and the ``errno`` variable is set +appropriately. The generic error codes are described at the +:ref:`Generic Error Codes <gen-errors>` chapter. |
