phy: core: fix wrong err handle for phy_power_on

2016-03-03T23:07:28+00:00

commit b82fcabe212a11698fd4b3e604d2f81d929d22f6 upstream. If phy_pm_runtime_get_sync failed but we already enable regulator, current code return directly without doing regulator_disable. This patch fix this problem and cleanup err handle of phy_power_on to be more readable. Fixes: 3be88125d85d ("phy: core: Support regulator ...")

phy: twl4030-usb: Fix unbalanced pm_runtime_enable on module reload

2016-02-25T20:01:14+00:00

commit 58a66dba1beac2121d931cda4682ae4d40816af5 upstream. If we reload phy-twl4030-usb, we get a warning about unbalanced pm_runtime_enable. Let's fix the issue and also fix idling of the device on unload before we attempt to shut it down. If we don't properly idle the PHY before shutting it down on removal, the twl4030 ends up consuming about 62mW of extra power compared to running idle with the module loaded.

phy: core: Get a refcount to phy in devm_of_phy_get_by_index()

2015-12-07T13:14:02+00:00

On driver detach, devm_phy_release() will put a refcount to the phy, so gets a refconut to it before return. Signed-off-by: Chunfeng Yun Signed-off-by: Kishon Vijay Abraham I

phy: cygnus: pcie: add missing of_node_put

2015-12-03T06:58:23+00:00

for_each_available_child_of_node performs an of_node_get on each iteration, so a return from the middle of the loop requires an of_node_put. A simplified version of the semantic patch that finds this problem is as follows (http://coccinelle.lip6.fr): // @@ expression root,e; local idexpression child; @@ for_each_available_child_of_node(root, child) { ... when != of_node_put(child) when != e = child ( return child; | * return ...; ) ... } // Signed-off-by: Julia Lawall Signed-off-by: Kishon Vijay Abraham I
