It's not really a fix for my patch though: the original code never
worked on mainline kernels because the w5100_spi_probe() function
always passed -EINVAL as the gpio number since it was first added in
630cf09751fe ("net: w5100: support SPI interface mode"). Arthur
correctly adds support for the link gpio line using DT probing.

I would suggest rewording the patch description to clarify this
by describing what the added code does first before mentioning
the removal of the old version.
