Subject[PATCH -next] ASoC: SOF: debug: fix possible memory leak in sof_dfsentry_write()
Date
'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")
