Subject: [PATCH AUTOSEL 4.14 19/21] irqchip/mbigen: Free msi_desc on device teardown
Date: Fri, 24 Apr 2020 08:24:17 -0400 [thread overview]
Message-ID: <20200424122419.10648-19-sashal@kernel.org> (raw)
In-Reply-To: <20200424122419.10648-1-sashal@kernel.org>
From: Zenghui Yu <yuzenghui@huawei.com>
[ Upstream commit edfc23f6f9fdbd7825d50ac1f380243cde19b679 ]
Using irq_domain_free_irqs_common() on the irqdomain free path will
leave the MSI descriptor unfreed when platform devices get removed.
Properly free it by MSI domain free function.
Fixes: 9650c60ebfec0 ("irqchip/mbigen: Create irq domain for each mbigen device")
