[PATCH 2/6] media: renesas-ceu: keep input name simple

[Hans Verkuil <hverkuil-cisco@xxxxxxxxx>]

Just show the Camera index as input name in VIDIOC_ENUM_INPUT,
no need to show the subdev name as well as that is meaningless for
users anyway.

This fixes this compiler warning:

drivers/media/platform/renesas/renesas-ceu.c: In function 'ceu_enum_input':
