Subject: [PATCH AUTOSEL 5.7 183/388] ASoC: SOF: core: fix error return code in sof_probe_continue()

From: Wei Yongjun <weiyongjun1@...wei.com>

[ Upstream commit 7d8785bc7adbb4dc5ba8ee06994107637848ded8 ]

Fix to return negative error code -ENOMEM from the IPC init error
handling case instead of 0, as done elsewhere in this function.
