Jon Hunter 015798b2f1 USB: EHCI: ensure all watchdog timer events are deleted when suspending usb ... This patch was previously discussed in the following thread: http://thread.gmane.org/gmane.linux.usb.general/19472/focus=19484 On the OMAP3 device the usbhost controller is in a separate internal power-domain. So when the usbhost is inactive or suspend is called, we can disable clocks and power-down the usbhost to save power. Recently we found that after calling ehci_bus_suspend() and disabling the usbhost clocks we would see the ehci watchdog timer event fire. This was causing a kernel panic because the usbhost controllers clocks were disabled and inside the watchdog timer function the clocks were not being re-enabled, so when the ehci registers were accessed this resulted in a CPU data-abort. To avoid this panic, per recommendation from Alan Stern (see above thread), we make sure any pending timer events (that may have been scheduled by calling ehci_work within the ehci_bus_suspend() function) are deleted before returning.
