Subject: [PATCH v3 2/3] LoongArch: KVM: Propagate real error code in kvm_pch_pic_create
Date: Wed, 14 Oct 2026 13:29:32 +0800 [thread overview]
Message-ID: <20261014052933.723303-3-cui.tao@linux.dev> (raw)
In-Reply-To: <20261014052933.723303-1-cui.tao@linux.dev>
From: Tao Cui <cuitao@kylinos.cn>
kvm_pch_pic_create() replaces the real error of
kvm_setup_default_irq_routing() with a fixed -ENOMEM. Return the
actual code, as kvm_eiointc_create() already does; the kvm_ipi_create()
case is fixed separately by "Return the actual error code in
kvm_ipi_create()" (Chaithanya Lagisetty).
Fixes: e785dfacf7e7 ("LoongArch: KVM: Add PCHPIC device support")
