That would still test the wrong bitfield. And all that is obsolete anyway since commit 5b64c173cd (of Sep 2015).

[PATCH] ASoC : fsl_ssi : Correct the condition to check AC97 mode
Corrected the condition to check if ssi is configured for AC97 mode. Other modes like dsp_a also satisfy the ANDing condition.
