[ Upstream commit 4b592061f7b3971c70e8b72fc42aaead47c24701 ]
In the original commit 9a34b45397e5 ("clk: Add support for runtime PM"), the commit message mentioned that pm_runtime_put_sync() would be done at the end of clk_core_unprepare(). This mirrors the operations in clk_core_prepare() in the opposite order.
However, the actual code that was added wasn't in the order the commit message described. Move clk_pm_runtime_put() to the end of clk_core_unprepare() so that it is in the correct order.
