[PATCH 02/14] net: mt7628-eth: check dev_remap_addr_index() for NULL

[David Lechner]

Check the return value of dev_remap_addr_index() for NULL instead of
IS_ERR(). This function only ever returns NULL on failure.

Replace the now-unused <linux/err.h> include with <errno.h>,
which is what actually provides the error codes this driver uses.

Fixes: c895ef465059 ("net: Add MT7628 ethernet driver")
