Subject: ARM: sa11x0: neponset: get parent IRQ from neponset device resource
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=b6bdfcf5ae634fcb9dce0c16972cf39d90be6f74;p=deliverable%2Flinux.git

ARM: sa11x0: neponset: get parent IRQ from neponset device resource

Obtain the parent IRQ from the neponset device resource rather than
hard-coding it into the code.
