[RFC PATCH 0/3] Enable support for error detection in CSI2RX

[Yemike Abhilash Chandra]

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.
