Subject: media: ti-vpe: cal: Use correct device name for bus_info
X-Git-Tag: v5.15~3158^2~136
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=17513da19e0a170d0a63c6c80e5d88cbf3eb1788;p=platform%2Fkernel%2Flinux-starfive.git

media: ti-vpe: cal: Use correct device name for bus_info

The v4l2_capability bus_info field, filled by the VIDIOC_QUERYCAP ioctl
handler, specifies the location of the device in the system. For
platform devices, V4L2 specifies that the value must be "platform:"
followed by the device name. Fix the cal_querycap() function to set the
right value.
