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. Changelog: Changes in v2: - Address Krzysztof's review comment to remove flexibility while adding interrupts. - Address Jai's review comment to drop support VIDIOC_LOG_STATUS on a video node. - Address Jai's review comment to get interrupt at probe instead of start_stream. - Address Jai's review comment to change dev_warn to dev_dbg when there is no interrupt defined in DT.
