[GitHub] [nuttx] davids5 commented on pull request #8185: Acknowledge interrupt before installing callback

   It is service and device dependent. The normal sequence is to enable from NVIC outward. (Disable in the opposite direction)
   
   1. attach
   2. enable NVIC
   3. enable device.
   4. 
   
   If this change were to come in it would break async code. Like in the SDMMC driver switching to event wait on D0 for write completion. We want to service the interrupt if it happens before we switch modes. The service should deal with it.
