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 ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
