[PATCH] of: device: Fix missing of_node_put() in of_dma_set_restricted_buffer

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

 



We should use of_node_put() for the reference 'node' returned by
of_parse_phandle() which will increase the refcount.

Fixes: fec9b625095f ("of: Add plumbing for restricted DMA pool")
