ASoC: SOF: debug: fix possible memory leak in sof_dfsentry_write()
'string' is malloced in sof_dfsentry_write() and should be freed before leaving from the error handling cases, otherwise it will cause memory leak. Fixes: 091c12e1f50c ("ASoC: SOF: debug: add new debugfs entries for IPC flood test") Signed-off-by: Wei Yongjun <weiyongjun1@huawei.com> Reviewed-by: Ranjani Sridharan <ranjani.sridharan@linux.intel.com> Link: https://lore.kernel.org/r/20190705081637.157169-1-weiyongjun1@huawei.com Signed-off-by: Mark Brown <broonie@kernel.org>
