Subject: [PATCH v4 2/7] media: i2c: imx335: Fix logging line endings
Date:   Mon, 11 Dec 2023 18:29:44 +0530

From: Kieran Bingham <kieran.bingham@ideasonboard.com>

The use of \n as a line ending throughout the driver is inconsistent.

While it is possible for logging messages to automatically have newlines
added by the kernel printk mechanisms, this is specifically to support
continued lines with PR_CONT and the lack of a new line character
indicates that the text is a fragment of a continuation line.

As each of these lines are whole and not fragments, explicitly define the
newline for consistency.
