If anyone has any objections, please let me know. ------------------ From: Jorge Ramirez-Ortiz commit 3200144a2fa4209dc084a19941b9b203b43580f0 upstream. Make sure the interrupt handler is initialized before the interrupt is registered. If the IRQ is registered before hfi_create(), it's possible that an interrupt fires before the handler setup is complete, leading to a NULL dereference. This error condition has been observed during system boot on Rb3Gen2.
