[PATCH] ASoC: stm32: spdifrx: Delete unnecessary check in the probe function
From: Tang Bin
Date: Wed Aug 11 2021 - 07:55:04 EST
The function stm32_spdifrx_parse_of() is only called by the function
stm32_spdifrx_probe(), and the probe function is only called with
an openfirmware platform device. Therefore there is no need to check
the device_node in probe function.
