Subject[PATCH 4.9 013/171] soc: fsl: qe: Fix copy/paste bug in ucc_get_tdm_sync_shift()
Date
4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

[ Upstream commit 96fc74333f84cfdf8d434c6c07254e215e2aad00 ]

There is a copy and paste bug so we accidentally use the RX_ shift when
we're in TX_ mode.

Fixes: bb8b2062aff3 ("fsl/qe: setup clock source for TDM mode")
