BTW, the API is directly used by below source files in error handling path, so also fix relevant issue within these source files: drivers/pci/controller/cadence/pcie-cadence.c drivers/net/ethernet/ti/am65-cpsw-nuss.c Fixes: ff764963479a ("drivers: phy: add generic PHY framework") Cc: stable@vger.kernel.org Cc: netdev@vger.kernel.org Cc: linux-pci@vger.kernel.org Signed-off-by: Zijun Hu --- drivers/phy/phy-core.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/phy/phy-core.c b/drivers/phy/phy-core.c index f053b525ccff..f190d7126613 100644 --- a/drivers/phy/phy-core.c +++ b/drivers/phy/phy-core.c @@ -737,7 +737,7 @@ void devm_phy_put(struct device *dev, struct phy *phy) if (!phy) return; - r = devres_destroy(dev, devm_phy_release, devm_phy_match, phy); + r = devres_release(dev, devm_phy_release, devm_phy_match, phy); dev_WARN_ONCE(dev, r, "couldn't find PHY resource\n"); } EXPORT_SYMBOL_GPL(devm_phy_put);
