[PATCH V4] ASoC: fsl_esai: Fix missing break in switch statement

[S.j. Wang]

case ESAI_HCKT_EXTAL and case ESAI_HCKR_EXTAL should be
independent of each other, so replace fall-through with break.

Fixes: 43d24e76b698 ("ASoC: fsl_esai: Add ESAI CPU DAI driver")

You should preserve the changelog of what has changed in each version, not only
the last changes, so that there is a logical flow and the maintainers do not
have to dig up previous versions:

Changes in v3:
- Update subject line.

Changes in v2:
- Fix "Fixes" tag.


Also, for this type of fixes, make sure to always Cc lkml: linux-kernel@vger.kernel.org

Thanks

Since it is obvious that you will need to send v5 please remove the new line
between Fixes and Signed-off-by. This is a common practice and some tools
might depend on this to parse the Fixes tag.
