ASoC: Intel: Fix use of potentially uninitialized variable
commit 810f3b860850148788fc1ed8a6f5f807199fed65 upstream.
If ipc->ops.reply_msg_match is NULL, we may end up using uninitialized
mask value.
reported by smatch:
sound/soc/intel/common/sst-ipc.c:266 sst_ipc_reply_find_msg() error: uninitialized symbol 'mask'.
