Subject: sound/soc/fsl/fsl_dma.c: add missing of_node_put
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=81a081fff7f3c144a0da9ee726906e533f66dd89;p=linux-beck.git

sound/soc/fsl/fsl_dma.c: add missing of_node_put

of_parse_phandle increments the reference count of np, so this should be
decremented before trying the next possibility.

Since we don't actually use np, we can decrement the reference count
immediately.
