+Subject: ASoC: pcm: free path list before exiting from error conditions
+
+From: Patrick Lai <plai@codeaurora.org>
+
+commit e4ad1accb28d0ed8cea6f12395d58686ad344ca7 upstream.
+
+dpcm_path_get() allocates dynamic memory to hold path list.
+Corresponding dpcm_path_put() must be called to free the memory.
+dpcm_path_put() is not called under several error conditions.
+This leads to memory leak.
