Subject: [PATCH 01/23] media: imx: imx7_mipi_csis: Fix logging of only error event counters
Date: Tue, 13 Apr 2021 05:29:52 +0300	[thread overview]
Message-ID: <20210413023014.28797-2-laurent.pinchart@ideasonboard.com> (raw)
In-Reply-To: <20210413023014.28797-1-laurent.pinchart@ideasonboard.com>

The mipi_csis_events array ends with 6 non-error events, not 4. Update
mipi_csis_log_counters() accordingly. While at it, log event counters in
forward order, as there's no reason to log them backward.
