Subject: [PATCH v2] devres: fix devres_get()

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")
Signed-off-by: Masahiro Yamada <yamada.masahiro@...ionext.com>
Acked-by: Tejun Heo <tj@...nel.org>
---

Changes in v2:
  - Fix "Fixes: " tag format ("Fixes: commit ... -> Fixes: ...)
  - Add Tejun's Acked-by
  - Cc stable@...r.kernel.org
