'netdev' is a managed resource allocated in the probe using
'devm_alloc_etherdev()'.
It must not be freed explicitly in the remove function.

The print function dev_err() is redundant because
platform_get_irq() already prints an error.

Current settings may produce a build error when
CONFIG_OF_NET is disabled. The CONFIG_OF_NET controls
a headfile <linux/of.h> and some functions

LiteX is a soft system-on-chip that targets FPGAs. LiteETH is a basic
network device that is commonly used in LiteX designs.
The driver was first written in 2017 and has been maintained by the
LiteX community in various trees. Thank you to all who have contributed.
