[PATCH] ASoC: arizona: Wait for resume before enabling FLL

[PATCH] ASoC: arizona: Wait for resume before enabling FLL

[Richard Fitzgerald]

When enabling an FLL use pm_runtime_get_sync() instead of
pm_runtime_get() to ensure that all the register settings
have been written out and the codec is powered-up before
we write the enable bit.
