Subject: [PATCH] genirq: Add IRQ 0 to domain debug file
Date: Sat, 15 Nov 2014 14:27:20 +0300 [thread overview]
Message-ID: <1416050840-24721-1-git-send-email-dbaryshkov@gmail.com> (raw)
Currently irq_domain_mapping debugfs file dumps IRQ information starting
from IRQ 1. IRQ 0 is missing from that file. Add it to have the complete
picture of IRQ/domains mappings.
