Revision 1401cf600d548c72f51e20b5841c330d5c11c9e2 authored by Wei Yongjun on 20 May 2020, 03:41:16 UTC, committed by David S. Miller on 22 May 2020, 00:14:18 UTC
Convert to using IS_ERR() instead of NULL test for cpsw_ale_create()
error handling. Also fix to return negative error code from this error
handling case instead of 0 in.
