Subjectlinux-next: build failure after merge of the net-next tree
Hi all,

After merging the net-next tree, today's linux-next build (arm
multi_v7_defconfig) failed like this:

lib/rhashtable.c: In function 'rhashtable_walk_next':
lib/rhashtable.c:1002:3: error: implicit declaration of function 'ERR_PTR' [-Werror=implicit-function-declaration]
return ERR_PTR(-EAGAIN);
^
lib/rhashtable.c:1002:3: warning: return makes pointer from integer without a cast

Caused by commit f2dba9c6ff0d ("rhashtable: Introduce
rhashtable_walk_*"). See Rule 1 in Documentation/SubmitChecklist.

I have added the following fix patch for today:

From: Stephen Rothwell <sfr@canb.auug.org.au>
