[PATCH 5.4 137/183] media: rename VFL_TYPE_GRABBER to _VIDEO

24 Mar 2024

From: Hans Verkuil hverkuil-cisco@xs4all.nl
[ Upstream commit 238e4a5baa361256ae1641ad9455bb2bb359273f ]
We currently have the following devnode types:
enum vfl_devnode_type {
        VFL_TYPE_GRABBER        = 0,
        VFL_TYPE_VBI,
        VFL_TYPE_RADIO,
        VFL_TYPE_SUBDEV,
        VFL_TYPE_SDR,
        VFL_TYPE_TOUCH,
        VFL_TYPE_MAX /* Shall be the last one */
};
They all make sense, except for the first: GRABBER really refers to /dev/videoX
devices, which can be capture, output or m2m, so 'grabber' doesn't even refer to
their function anymore.
Let's call a spade a spade and rename this to VFL_TYPE_VIDEO.
