Subject: [PATCH] firmware: imx: scu: Fix possible memory leak in imx_scu_probe()
Git-commit: 89f12d6509bff004852c51cb713a439a86816b24
Patch-mainline: v5.8-rc1
References: bsc#1111666
'chan_name' is malloced in imx_scu_probe() and should be freed
before leaving from the error handling cases, otherwise it will
cause memory leak.
