Subject: [PATCH 3/6] phy: core: Fix API devm_phy_destroy() can not destroy
 the phy

From: Zijun Hu <quic_zijuhu@...cinc.com>

For devm_phy_destroy(), its comment says it needs to invoke phy_destroy()
to destroy the phy, but it does not do that actually, so it can not fully
undo what the API devm_phy_create() does, that is wrong, fixed by using
devres_release() instead of devres_destroy() within the API.

Fixes: ff764963479a ("drivers: phy: add generic PHY framework")
