If anyone has any objections, please let me know. ------------------ From: Zijun Hu commit fdce49b5da6e0fb6d077986dec3e90ef2b094b50 upstream. For devm_usb_put_phy(), its comment says it needs to invoke usb_put_phy() to release the phy, but it does not do that actually, so it can not fully undo what the API devm_usb_get_phy() does, that is wrong, fixed by using devres_release() instead of devres_destroy() within the API.
