      ipmi: kcs_bmc: fix IRQ exception if the channel is not open · dc0f0a02
      Haiyue Wang authored
      
      
      When kcs_bmc_handle_event calls kcs_force_abort function to handle the
      not open (no user running) KCS channel transaction, the returned status
      value -ENODEV causes the low level IRQ handler indicating that the irq
      was not for him by returning IRQ_NONE. After some time, this IRQ will
      be treated to be spurious one, and the exception dump happens.

      It needs to change the returned status from -ENODEV to 0. The -ENODEV
      was originally used to tell the low level IRQ handler that no user was
      running, but not consider the IRQ handling desgin.
      
      And multiple KCS channels share one IRQ handler, it needs to check the
      IBF flag before doing force abort. If the IBF is set, after handling,
      return 0 to low level IRQ handler to indicate that the IRQ is handled.

       "ipmi_si: Clean up shutdown a bit" didn't
      copy the behavior of the cleanup in one spot, it needed to
      check for a non-NULL interface before cleaning it up.
