Daniel Mack c03da38d5d usb: musb: use is_host_active() to distinguish between host and gadget mode ... On AM33xx platforms, unplugging a device in the middle of an active transfer leads to a drop of MUSB_DEVCTL_HM in MUSB_DEVCTL before the system is informed about a disconnect. This consequently makes the musb core call the gadget code to handle the interrupt request, which then crashes the kernel because the relevant pointers haven't been set up for gadget mode. To fix this, use is_host_active() rather than (devctl & MUSB_DEVCTL_HM) in musb_interrupt() and musb_dma_completion() to detect whether the controller is in host or peripheral mode. This information is provided by the driver logic and does not rely on register contents.
