Subject: [PATCH 1/2] gpio: tegra: create irq mapping in gpio_to_irq
Date: Wed, 7 Nov 2012 20:31:31 +0530 [thread overview]
Message-ID: <1352300492-24779-1-git-send-email-ldewangan@nvidia.com> (raw)
The gpio interrupts get mapped linearly and hence the mapping
of irq need to be created by irq_create_mapping().
The function gpio_to_irq() returns the irq by irq_find_mapping()
and so returns 0 as there is no mapping created. Fix the function
to create mapping when gpio_to_irq() get called.
