From 4446eb8dbeb223031fb652dd1e58e59d3d4b4aba Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Wed, 13 Feb 2019 11:56:50 +0300 Subject: lib: objagg: Fix an error code in objagg_hints_get() We need to set the error code on this path otherwise we return ERR_PTR(0) which would result in a NULL dereference in the caller.
