From: Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx> [ Upstream commit d8c3be2fb2079d0cb4cd29d6aba58dbe54771e42 ] This reverts commit 656025850074f5c1ba2e05be37bda57ba2b8d491. Because of recent interactions with developers from @umn.edu, all commits from them have been recently re-reviewed to ensure if they were correct or not. Upon review, this commit was found to be incorrect for the reasons below, so it must be reverted. It will be fixed up "correctly" in a later kernel change. Different error values should never be "OR" together and expect anything sane to come out of the result.
