This patch series enables the csi2rx_err_irq interrupt to record any errors
that occur during streaming. It also adds support for the VIDIOC_LOG_STATUS
ioctl, which outputs the current device status to the kernel log.

The IRQ handler records any errors encountered during streaming.
Additionally, VIDIOC_LOG_STATUS can be invoked from user space to retrieve
the latest status.

Logs without interrupt in DT: https://gist.github.com/Yemike-Abhilash-Chandra/d807230b2a624b7a38effed89efdd148
