patch "fsi: scom: Don't abort operations for minor errors" added to char-misc-linus

These errors won't impact the ability of the scom engine to perform operations, so the driver should continue under these conditions.

Nevertheless we cannot be sure that any pending URB has already finished, so although they will never succeed, they still must not be touched. The clean solution for this is to check for WDM_IN_USE and WDM_DISCONNECTED in flush(). There is no point in ever clearing WDM_IN_USE, as no further writes make sense.

In other hand, ohci_irq() is possible to enable OHCI_INTR_SF and OHCI_INTR_MIE on ohci_irq(). Note that OHCI_INTR_SF is possible to be set by start_ed_unlink() which is called: ohci_irq() -> process_done_list() -> takeback_td() -> start_ed_unlink() So, ohci_irq() has the following condition, the issue happens by &ohci->regs->intrenable = OHCI_INTR_MIE | OHCI_INTR_SF and ohci->rh_state = OHCI_RH_HALTED: /* interrupt for some other device? */ if (ints == 0 || unlikely(ohci->rh_state == OHCI_RH_HALTED)) return IRQ_NOTMINE; To fix the issue, ohci_shutdown() holds the spin lock while disabling the interruption and changing the rh_state flag to prevent reenable the OHCI_INTR_MIE unexpectedly. Note that io_watchdog_func() also calls the ohci_shutdown() and it already held the spin lock, so that the patch makes a new function as _ohci_shutdown().

If managed device resources are not used then "parent" resource is released before subrange at driver removal as .remove callback is called before the devres list of resources for this device is walked and released. This has been observed with the xhci extended capability driver causing a use-after-free which is now fixed. An additional nice benefit is that error handling on driver initialisation is simplified much.
