Subject: coresight: Remove erroneous dma_free_coherent in tmc_probe

From: Suzuki K Poulose <[email protected]>

commit 481e46fe7a88557b66330cbb047b25cc13eff4b9 upstream.

commit de5461970b3e9e194 ("coresight: tmc: allocating memory when needed") removed the static allocation of buffer for the trace data in ETR mode in tmc_probe. However it failed to remove the "devm_free_coherent" in tmc_probe when the probe fails due to other reasons. This patch gets rid of the incorrect dma_free_coherent() call.
