Subject: dm: error handling dev_get_dma_range()
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=c803838fa85d681a0ea60409fc81f596a2e9c07c;p=u-boot.git

dm: error handling dev_get_dma_range()

goto after return has not effect. Calling of_node_put() in case of some
errors and not for others is inconsistent.

Fixes: 51bdb50904b ("dm: Introduce xxx_get_dma_range()")
