drivers/soc/lantiq/gphy.c: In function âxway_gphy_removeâ:
drivers/soc/lantiq/gphy.c:198:6: warning: unused variable âretâ [-Wunused-variable]
  int ret;
      ^~~
drivers/soc/lantiq/gphy.c:196:17: warning: unused variable âdevâ [-Wunused-variable]
  struct device *dev = &pdev->dev;
                 ^~~

Easily fixed, I can drop those two lines:

diff --git a/drivers/soc/lantiq/gphy.c b/drivers/soc/lantiq/gphy.c
index 8c31ae750987..feeb17cebc25 100644

+++ b/drivers/soc/lantiq/gphy.c
@@ -193,9 +193,7 @@ static int xway_gphy_probe(struct platform_device *pdev)

 {
-	struct device *dev = &pdev->dev;
	struct xway_gphy_priv *priv = platform_get_drvdata(pdev);
-	int ret;

	iowrite32be(0, priv->membase);

However it does raise the question, it sounds like a fix, but was this
patch tested and the warning just overlooked?

Cheers
James
