    [PATCH] USB: EHCI updates · f03c17fc
    David Brownell 提交于
    This fixes some bugs in EHCI suspend/resume that joined us over the past
    few releases (as usbcore, PCI, pmcore, and other components evolved):
    
      - Removes suspend and resume recursion from the EHCI driver, getting
        rid of the USB_SUSPEND special casing.
    
      - Updates the wakeup mechanism to work again; there's a newish usbcore
        call it needs to use.
    
      - Provide simpler tests for "do we need to restart from scratch", to
        address another case where PCI Vaux was lost.  (In this case it was
        restoring a swsusp snapshot, but there could be others.)
    
    Un-exports a symbol that was temporarily exported.
    
    A notable change from previous version is that this doesn't move
    the spinlock init, so there's still a resume/reinit path bug.
