Same issue as last time, double function.

Please run scripts/checkpatch.pl and fix reported warnings. Then please
run 'scripts/checkpatch.pl --strict' and (probably) fix more warnings.
Some warnings can be ignored, especially from --strict run, but the code
here looks like it needs a fix. Feel free to get in touch if the warning
is not clear.

Are you sure it works? I see 12 items in fsl-ls1088a.dtsi.

What's more, I do not see your errors/warnings at all.
