Merge branch 'net-ethernet-ti-fix-some-return-value-check'
 
Wei Yongjun says:

====================
net: ethernet: ti: fix some return value check

This patchset convert cpsw_ale_create() to return PTR_ERR() only, and
changed all the caller to check IS_ERR() instead of NULL.

Since v2:
1) rebased on net.git, as Jakub's suggest
2) split am65-cpsw-nuss.c changes, as Grygorii's suggest
====================
