Subject: [PATCH] soc: ti: pm33xx: Fix refcount leak in am33xx_pm_probe
Git-commit: 8f3c307b580a4a6425896007325bddefc36e8d91
Patch-mainline: v6.4-rc1
References: git-fixes
wkup_m3_ipc_get() takes refcount, which should be freed by
wkup_m3_ipc_put(). Add missing refcount release in the error paths.
Fixes: 5a99ae0092fe ("soc: ti: pm33xx: AM437X: Add rtc_only with ddr in self-refresh support")
