[ Upstream commit cb36ff785e868992e96e8b9e5a0c2822b680a9e2 ]
The content of SND_SOC_DAIFMT_FORMAT_MASK is a number, not a bitfield,
so the test to check if the format is i2s is wrong. Because of this the
clock setting may be wrong. For example, the sample clock gets inverted
in DSP B mode, when it should not.
Fix the lrclk invert helper function
