[PATCH 3.10 16/20] devres: fix devres_get()

From: Greg Kroah-Hartman
Date: Sat Sep 19 2015 - 14:38:54 EST


3.10-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")
