ASoC: meson: axg-tdm: fix sample clock inversion

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 Fixes: 1a11d88 ("ASoC: meson: add tdm formatter base driver") Signed-off-by: Jerome Brunet <[email protected]> Signed-off-by: Mark Brown <[email protected]>
