Subject: net: moxa: Fix a potential double 'free_irq()'
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=ee8d2267f0e39a1bfd95532da3a6405004114b27;p=linux.git

net: moxa: Fix a potential double 'free_irq()'

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")
