extcon: palmas: Check the parent instance to prevent the NULL

2017-12-07T02:20:09Z

[ Upstream commit 9fe172b9be532acc23e35ba693700383ab775e66 ] extcon-palmas must be child of palmas and expects parent's drvdata to be valid. Check for non NULL parent drvdata and fail if it is NULL. Not doing so will result in a NULL pointer dereference later in the probe() parent drvdata is NULL (e.g. misplaced extcon-palmas node in device tree).

extcon: palmas: Use devm_extcon_dev_register()

2014-04-24T10:37:05Z

Use the resource-managed extcon device register function (i.e. devm_extcon_dev_register()) instead of extcon_dev_register(). If extcon device is attached with this function, that extcon device is automatically unregistered on driver detach. That reduces tiresome managing code.

extcon: palmas: explicitly set edev name as node name

2014-04-22T06:41:10Z

commit ca488 (extcon: of: Remove unnecessary function call by using the name of device_node) started using node name instead of device name to get the extcon device. This breaks dwc3-omap since it's not able to get the extcon device anymore. Fixed it by setting edev name of palmas to be the same as its node name.

extcon: palmas: Handle ID interrupt properly using USB_ID_INT_SRC

2014-01-07T02:54:27Z

Always cross check with the ID state and the source of interrupt. Also add a case in which ID Source is ID_GND but LATCH state is set wrongly. This uses the previous Link stat to determine the new state. Signed-off-by: George Cherian Acked-by: Laxman Dewangan Signed-off-by: Chanwoo Choi
