X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=2974a35657bf73db154c0173d3061812716f4e00;p=linux-beck.git

MIPS: JZ4740: use generic plat_irq_dispatch

Make use of the generic plat_irq_dispatch function introduced by commit
85f7cdacbb81 "MIPS: Provide a generic plat_irq_dispatch", in order to
reduce unnecessary code duplication.
