[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Masahiro Yamada <yamada.masahiro@xxxxxxxxxxxxx>

This patch has been added to the 3.12 stable tree. If you have any
objections, please let us 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")
