genirq: Make irq_domain_alloc_descs() non static
We will need to use this function to implement irq_reserve_ipi() later. So make it non static and move the prototype to irqdomain.h to allow using it outside irqdomain.c Signed-off-by: Qais Yousef <qais.yousef@imgtec.com> Cc: <jason@lakedaemon.net> Cc: <marc.zyngier@arm.com> Cc: <jiang.liu@linux.intel.com> Cc: <ralf@linux-mips.org> Cc: <linux-mips@linux-mips.org> Cc: <lisa.parratt@imgtec.com> Cc: Qais Yousef <qsyousef@gmail.com> Link: http://lkml.kernel.org/r/1449580830-23652-8-git-send-email-qais.yousef@imgtec.com Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
