Subject: [PATCH 4.9 07/25] xtensa: call irqchip_init only when CONFIG_USE_OF is selected
Date: Thu, 14 Oct 2021 16:53:38 +0200 [thread overview]
Message-ID: <20211014145207.811181114@linuxfoundation.org> (raw)
In-Reply-To: <20211014145207.575041491@linuxfoundation.org>

[ Upstream commit 6489f8d0e1d93a3603d8dad8125797559e4cf2a2 ]
During boot time kernel configured with OF=y but USE_OF=n displays the
following warnings and hangs shortly after starting userspace:
------------[ cut here ]------------

Failed to request irq 0 (timer)
Fix that by calling irqchip_init only when CONFIG_USE_OF is selected and
calling legacy interrupt controller init otherwise.
