Subject: [PATCH v2 9/9] watchdog: rzv2h_wdt: Improve error strings and add newlines

From: Lad Prabhakar <prabhakar.mahadev-lad.rj@...renesas.com>

Update rzv2h_wdt_probe() to provide clearer error strings when retrieving
the pclk, oscclk, and reset controller, and append missing newline
characters to dev_err_probe() and dev_warn() calls for proper log
formatting.
