Subject: [net-next,PATCH v6 5/8] net: stmmac: dwmac-stm32: Clean up the debug prints
Date: Mon, 10 Jun 2024 09:14:56 +0200

From: Marek Vasut <marex@denx.de>

Use dev_err()/dev_dbg() and phy_modes() to print PHY mode instead of
pr_debug() and hand-written PHY mode decoding. This way, each debug
print has associated device with it and duplicated mode decoding is
removed.
