[PATCH 2/2] fsl/qe: Cleanup error paths in ucc_of_parse_tdm()

[Dan Carpenter <dan.carpenter@xxxxxxxxxx>]

The most important part of this change is that it not propogates error
codes instead of returning -EINVAL.  There was also a tab missing, and
a couple other minor cleanups which don't affect runtime.

Not tested, but I don't think propogating the errors will cause a
problem.
