Subject: at86rf230: use devm_request_irq
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=652355c5bd9430d7c382579f2bcd223bc47dd7e7;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

at86rf230: use devm_request_irq

This patch replace request_irq with devm_request_irq. With
devm_request_irq we don't need to care about freeing the irq.
