We need to bail out if lan78xx_get_endpoints() fails, otherwise the
result is overwritten.

[PATCH V2 2/4 next] net: lan78xx: Drop unnecessary strcpy in lan78xx_probe

From: Stefan Wahren <hidden>
Date: 2018-09-04 17:30:05

There is no need for this strcpy because alloc_etherdev() already
does this job.
