Subject: [PATCH] irqchip: Select downstream irqchip drivers for LoongArch CPU
Date: Mon,  8 Aug 2022 16:53:19 +0800	[thread overview]
Message-ID: <20220808085319.3350111-1-chenhuacai@loongson.cn> (raw)

LoongArch irqchips have a fixed hierarchy which currently can't be
described by ACPI tables, so upstream irqchip drivers call downstream
irqchip drivers' initialization directly. As a result, the top level
(CPU-level) irqchip driver should explicitly select downstream drivers
to avoid build errors.

Reported-by: kernel test robot <lkp@intel.com>
