list_entry() will never return a NULL pointer, thus remove the
check.

Hi Yuesong Li,

Thanks for your patch.

Some minor points about process.

1. As a Networking patch, that is not a bug fix, it should
   be explicitly targeted at net-next.

   Subject: [PATCH net-next] ...

2. Looking at git history, it looks like 'et131x' would be an appropriate
   prefix for this patch.

   Subject: [PATCH net-next] et131x: ...

Please consider reading
https://docs.kernel.org/process/maintainer-netdev.html

And, please post a v2, addressing the above, and including Mark's tag,
after waiting 24h from the initial patch posting (as described in the link
above). Please do so as a new email thread.

FWIIW, the code change itself looks good to me.

...
