media: rename VFL_TYPE_GRABBER to _VIDEO
[ 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.
