+Subject: ASoC: qdsp6: q6asm: do not sleep while atomic
+
+From: Srinivas Kandagatla <srinivas.kandagatla@oss.qualcomm.com>
+
+commit fdbb53d318aa94a094434e5f226617f0eb1e8f22 upstream.
+
+For some reason we ended up kfree between spinlock lock and unlock,
+which can sleep.
+
+move the kfree out of spinlock section.
+
+Fixes: a2a5d30218fd ("ASoC: qdsp6: q6asm: Add support to memory map and unmap")
