| Subject: clk: highbank: fix refcount leak in hb_clk_init() |
| |
| From: Yangtao Li <tiny.windzz@gmail.com> |
| |
| [ Upstream commit 5eb8ba90958de1285120dae5d3a5d2b1a360b3b4 ] |
| |
| The of_find_compatible_node() returns a node pointer with refcount |
| incremented, but there is the lack of use of the of_node_put() when |
| done. Add the missing of_node_put() to release the refcount. |
