Subject: [PATCH] media: mc: Get media_device directly from pad
References: bsc#1012628
Patch-mainline: 6.2.3
Git-commit: a967a3a788028f541e4db54beabcebc3648997db
[ 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")
