[ Upstream commit 0325cc0ac7980e1c7b744aab8df59afab6daeb43 ]

The pm_runtime_enable will increase power disable depth. Thus
a pairing decrement is needed on the error handling path to
keep it balanced according to context. We fix it by moving
pm_runtime_enable to the endding of stm32_spdifrx_probe.

Fixes:ac5e3efd55868 ("ASoC: stm32: spdifrx: add pm_runtime support")
