#     powerpc/powernv: Fix NVRAM sleep in invalid context when crashing
#     
#     Similarly to opal_event_shutdown, opal_nvram_write can be called in
#     the crash path with irqs disabled. Special case the delay to avoid
#     sleeping in invalid context.
#     
#     Fixes: 3b8070335f75 ("powerpc/powernv: Fix OPAL NVRAM driver OPAL_BUSY loops")
