CNS3xxx: Fix a WARN() related to IRQ allocation.
WARNING: at drivers/irqchip/irq-gic.c:952 gic_init_bases+0xe4/0x2b8() Cannot allocate irq_descs @ IRQ16, assuming pre-allocated Backtrace: gic_init_bases from cns3xxx_init_irq+0x24/0x34 cns3xxx_init_irq from init_IRQ+0x24/0x2c init_IRQ from start_kernel+0x1a8/0x338 start_kernel from 0x2000806c The problem is that 64 CNS3xxx CPU interrupts, starting at 32, are allocated by the ARM platform-independent code (as requested by machine_desc->nr_irqs = 96), and then the GIC code tries to allocate them again. Tested on Gateworks Laguna board, masqueraded as CNS3420VB. Signed-off-by: Krzysztof Hałasa <khalasa@piap.pl> Signed-off-by: Arnd Bergmann <arnd@arndb.de>
