Using priv->reset in this driver currently requires an IS_ERR check beforehand.
When I wrote the driver originally I used the following code in
phy_meson8b_usb2_probe:
priv->reset = ...
if (PTR_ERR(priv->reset) == -EPROBE_DEFER)
return PTR_ERR(priv->reset);
That means: priv->reset can (in theory) be an error pointer at runtime.
Since your patch is valid: can you please add another one (before this
one) in the series and change the priv->reset error checking to use
something like:
if (IS_ERR(priv->reset))
return dev_err_probe(&pdev->dev, PTR_ERR(priv->reset), "Failed to
get the reset line");
With such a patch you can consider this one as:
