If anyone has any objections, please let me know. ------------------ From: Konrad Dybcio [ Upstream commit 112c23705c6dc59a05290c8e3e597e1b4e9c23fc ] There are two instances of the POWER_STATE_CONFIG1 register: one in the PCS space and another one in PCS_USB. The downstream init sequence pokes the latter one while we've been poking the former one (and misnamed it as the latter one, impostor!). Fix that up to avoid UB.
