   4 Subject: [PATCH 087/102] net-next: mediatek: disable all interrupts during
   5  probe
   6
   7 The current code only disables those IRQs that we will later use. To
   8 ensure that we have a predefined state, we really want to disable all IRQs.
   9 Change the code to disable all IRQs to achieve this.
