Hi Joe,

Current implementation of adsp_probe() does not remove the subdevs of
struct qcom_adsp *adsp on the error path. Fix this bug by calling
qcom_remove_{ssr,sysmon,pdm,smd,glink}_subdev(), qcom_q6v5_deinit(), and
adsp_unassign_memory_region() appropriately.
Fixes: 5b9f51b200dc ("remoteproc: qcom: enable in-kernel PD mapper")
The ssr, sysmon, glink subdevs and qcom_q6v5_init() are the calls that
leak resources. I think this issue existed before the in-kernel PD
mapper patches so this Fixes tag isn't accurate.
Would this apply to the other remoteproc files like qcom_q6v5_adsp.c?
