Subject: [PATCH 4.9 126/130] soc: ti: wkup_m3_ipc: Fix error return code in wkup_m3_ipc_probe()

4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

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

commit 36b29eb30ee0f6c99f06bea406c23a3fd4cbb80b upstream.

Fix to return a negative error code from the kthread_run() error
handling case instead of 0, as done elsewhere in this function.

Fixes: cdd5de500b2c ("soc: ti: Add wkup_m3_ipc driver")
