Subject: [PATCH AUTOSEL 4.4 08/14] net: moxa: Fix a potential double 'free_irq()'
Date: Thu, 14 May 2020 14:56:19 -0400	[thread overview]
Message-ID: <20200514185625.21753-8-sashal@kernel.org> (raw)
In-Reply-To: <20200514185625.21753-1-sashal@kernel.org>

From: Christophe JAILLET <christophe.jaillet@wanadoo.fr>

[ Upstream commit ee8d2267f0e39a1bfd95532da3a6405004114b27 ]

Should an irq requested with 'devm_request_irq' be released explicitly,
it should be done by 'devm_free_irq()', not 'free_irq()'.

Fixes: 6c821bd9edc9 ("net: Add MOXA ART SoCs ethernet driver")
