[PATCH AUTOSEL 5.4 4/4] mfd: arizona: Use pm_runtime_resume_and_get() to prevent refcnt leak

[Sasha Levin]

From: Liang He <windhl@xxxxxxx>

[ Upstream commit 4414a7ab80cebf715045e3c4d465feefbad21139 ]

In arizona_clk32k_enable(), we should use pm_runtime_resume_and_get()
as pm_runtime_get_sync() will increase the refcnt even when it
returns an error.
