  "A single fix targeting the MHI host stack:

    - Since the commit 1227d2a20cd7 ("bus: mhi: host: Move IRQ allocation to
      controller registration phase"), the MHI context gets freed during
      mhi_unregister_controller(). But when the MHI IRQs are shared, the IRQ
      handler may get invoked during __free_irq() if CONFIG_DEBUG_SHIRQ is set.
      In that case, there will be a null pointer dereference because of trying to
      use the freed context struct.

      So for fixing the issue, let's check for the existence of the context struct
      at the start of the handler before handling the IRQ."
