From b61789f53d49db8ca1f6b8fed411b317b4e8f044 Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Wed, 26 Jun 2019 05:58:02 -0400 Subject: [PATCH] media: drivers/media: don't set pix->priv = 0 The priv field of struct v4l2_pix_format shouldn't be set by drivers, it's set by the v4l2 core instead to V4L2_PIX_FMT_PRIV_MAGIC. Drop this from the few media drivers that still do this. Note that the gspca patch is slightly more involved since some of the sub-gspca drivers use the priv field internally.
