From b93804b2fcdb35cc45f95ad77cbe23cc620f6593 Mon Sep 17 00:00:00 2001 From: Lai Jiangshan Date: Fri, 6 Jun 2014 14:37:13 -0700 Subject: idr: fix idr_replace()'s returned error code When the smaller id is not found, idr_replace() returns -ENOENT. But when the id is bigger enough, idr_replace() returns -EINVAL, actually there is no difference between these two kinds of ids. These are all unallocated id, the return values of the idr_replace() for these ids should be the same: -ENOENT.
