[PATCH 5.4 036/108] clk: core: Fix runtime PM sequence in clk_core_unprepare()

[Greg Kroah-Hartman]

From: Chen-Yu Tsai <wenst@xxxxxxxxxxxx>

[ 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.

Fixes: 9a34b45397e5 ("clk: Add support for runtime PM")
