USB: chipidea: fix use after free bug

2012-11-26T22:59:00Z

The pointer to a platform_device struct must not be dereferenced after the device has been unregistered. This bug produces a crash when unloading the ci13xxx kernel module compiled with CONFIG_PAGE_POISONING enabled.

USB: chipidea: re-order irq handling to avoid unhandled irqs

2012-09-12T18:20:38Z

- let role driver handle irq before ID change check; this gives the role driver a chance to handle disconnect; - disable irq during switch role; no role driver to handle irq in the period.

USB: chipidea: acknowledge ID change interrupt in irq handler

2012-09-12T18:20:38Z

In order to avoid re-queueing of the role changing work, we need to clear the ID change interrupt bit right in the irq handler. Tested-by: Michael Grzeschik Tested-by: Marc Kleine-Budde Signed-off-by: Richard Zhao Signed-off-by: Alexander Shishkin Signed-off-by: Greg Kroah-Hartman

USB: chipidea: delay 2ms before read ID status at probe time

2012-09-12T18:20:38Z

The ID pin needs 1ms debounce time, even at probe time. We delay 2ms to be on the safe side. Tested-by: Michael Grzeschik Tested-by: Marc Kleine-Budde Signed-off-by: Richard Zhao Signed-off-by: Alexander Shishkin Signed-off-by: Greg Kroah-Hartman

usb: chipidea: permit driver bindings pass phy pointer

2012-07-09T16:59:23Z

Sometimes, the driver bindings may know what phy they use. For example, when using device tree, the usb controller may have a phandler pointing to usb phy. Signed-off-by: Richard Zhao Reviewed-by: Marek Vasut Acked-by: Felipe Balbi Tested-by: Subodh Nijsure Signed-off-by: Greg Kroah-Hartman
