Just noticed that you have
#define CTI_EE_MASK_OSC_FREQ_LOWER      GENMASK(15, 0)
#define CTI_EE_MASK_OSC_FREQ_UPPER      GENMASK(31, 16)

So, please modify them and the above check using these.
Something like

#define CTI_EE_MASK_OSC_FREQ		GENMASK(31, 0)

	osc_freq = le16_to_cpu(ee_words[0]) | (le16_to_cpu(ee_words[1]) << 16);
	if (osc_freq == CTI_EE_MASK_OSC_FREQ)
		return -EIO;

P.S> If I am not mistaken the definitions were only used in this function.
