[PATCH 6.1 506/885] media: mc: Get media_device directly from pad

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Laurent Pinchart <laurent.pinchart@xxxxxxxxxxxxxxxx>

[ Upstream commit a967a3a788028f541e4db54beabcebc3648997db ]

Various functions access the media_device from a pad by going through
the entity the pad belongs to. Remove the level of indirection and get
the media_device from the pad directly.

Fixes: 9e3576a1ae2b ("media: mc: convert pipeline funcs to take media_pad")
