[PATCHv2 18/23] media: am437x: don't fill in bus_info

[Hans Verkuil <hverkuil-cisco@xxxxxxxxx>]

Let the V4L2 core fill this in.

This fixes this warning:

drivers/media/platform/ti/am437x/am437x-vpfe.c: In function 'vpfe_querycap':
drivers/media/platform/ti/am437x/am437x-vpfe.c:1279:35: warning: '%s' directive output may be truncated writing up to 35 bytes into a region of size 23 [-Wformat-truncation=]
