[PATCH AUTOSEL 4.14 28/39] net: moxa: Fix a potential double 'free_irq()'

[Sasha Levin <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")
