[alsa-devel] [PATCH v2 2/2] topology: Fix the missing referenced elem ptr when merging private data

From: Mengdong Lin mengdong.lin@linux.intel.com

tplg_copy_data() should set the valid referenced data element pointer on success. The caller will double check this pointer for all kinds of references, including controls and data.
