[PATCH 3.12 27/84] devres: fix devres_get()

From: Jiri Slaby
Date: Fri Oct 02 2015 - 09:40:26 EST


From: Masahiro Yamada <yamada.masahiro@xxxxxxxxxxxxx>

3.12-stable review patch. If anyone has any objections, please let me know.

===============

commit 64526370d11ce8868ca495723d595b61e8697fbf upstream.

Currently, devres_get() passes devres_free() the pointer to devres,
but devres_free() should be given with the pointer to resource data.

Fixes: 9ac7849e35f7 ("devres: device resource management")
