In effect this hard-codes VFE indexes to power-domain indexes in the dtsi and mandates a very particular ordering of power domains in the dtsi, which bears no relationship to a real hardware dependency. As a first step to rationalising the VFE power-domain code and breaking the magic indexing in dtsi use per-VFE pointers to genpd linkages. The top-level index in msm_vfe_subdev_init is still used to attain the initial so no functional or logical change arises from this change.

Not always done but applicable to all. - device_link_add (DL_FLAG_STATELESS | DL_FLAG_PM_RUNTIME | DL_FLAG_RPM_ACTIVE); - Error check returning -EINVAL on error. - Return 0 Reduce the pattern down to a common callback. VFE 4.1 is a special case which to me also indicates that it is worthwhile maintaining an indirection for the vfe_pm_domain_{on|off} for now.
