Stefan Becker de85422b94 USB: fix interrupt disabling for HCDs with shared interrupt handlers ... USB: fix interrupt disabling for HCDs with shared interrupt handlers As has been discussed several times on LKML, IRQF_SHARED | IRQF_DISABLED doesn't work reliably, i.e. a shared interrupt handler CAN'T be certain to be called with interrupts disabled. Most USB HCD handlers use IRQF_DISABLED and therefore havoc can break out if they share their interrupt with a handler that doesn't use it. On my test machine the yenta_socket interrupt handler (no IRQF_DISABLED) was registered before ehci_hcd and one uhci_hcd instance. Therefore all usb_hcd_irq() invocations for ehci_hcd and for one uhci_hcd instance happened with interrupts enabled. That led to random lockups as USB core HCD functions that acquire the same spinlock could be called twice from interrupt handlers. This patch updates usb_hcd_irq() to always disable/restore interrupts. usb_add_hcd() will silently remove any IRQF_DISABLED requested from HCD code.
