From: Linus Walleij Date: Wed, 2 Jan 2013 21:30:56 +0000 (+0100) Subject: ARM: nomadik: bump the IRQ numbers again X-Git-Tag: firefly_0821_release~3680^2~1204^2~19^2 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=d9621176872319a568d9892701410bcbfbd5b35c;p=firefly-linux-kernel-4.4.55.git ARM: nomadik: bump the IRQ numbers again Bump the IRQ numbers from offset at 1 (right above NO_IRQ) to 32. This is the painful way to learn that if you're using SPARSE_IRQ and avoid to define .nr_irqs in your machine, the first 16 IRQs will be pre-allocated, and the IRQdomain code (as the VIC core code before it) will then assume that all IRQ descriptors are pre-allocated, and 16 of them are - by somebody else. So mapping the IRQs will fail in irq_create_mapping(). Moving the offset upward rids us of this problem.
