If anyone has any objections, please let me know. ------------------ From: Zijun Hu commit 4dc48c88fcf82b89fdebd83a906aaa64f40fb8a9 upstream. For devm_phy_destroy(), its comment says it needs to invoke phy_destroy() to destroy the phy, but it will not actually invoke the function since devres_destroy() does not call devm_phy_consume(), and the missing phy_destroy() call will cause that the phy fails to be destroyed. Fortunately, the faulty API has not been used by current kernel tree. Fix by using devres_release() instead of devres_destroy() within the API.
