[PATCH 3.19.y-ckt 026/156] devres: fix devres_get()
From: Kamal Mostafa
Date: Tue Oct 20 2015 - 17:39:16 EST
3.19.8-ckt8 -stable review patch. If anyone has any objections, please let me know.
------------------
From: Masahiro Yamada <yamada.masahiro@xxxxxxxxxxxxx>
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")
