Subject: irqchip/jcore-aic: Kill use of irq_create_strict_mappings()
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=5f8b938bd790cff6542c7fe3c1495c71f89fef1b;p=uclinux-h8%2Flinux.git

irqchip/jcore-aic: Kill use of irq_create_strict_mappings()

irq_create_strict_mappings() is a poor way to allow the use of
a linear IRQ domain as a legacy one. Let's be upfront about it.
