Subject: [PATCH] of/address: Introduce of_get_next_dma_parent() helper
|
|
|
|
commit 862ab5578f754117742c8b8c8e5ddf98bdb190ba upstream.
|
|
|
|
Add of_get_next_dma_parent() helper which is similar to
|
|
__of_get_dma_parent(), but can be used in iterators and decrements the
|
|
ref count on the prior parent.
