Subject: staging: comedi: ni_670x: remove spurious free_irq() call
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=604d66ce56ee8b31f32353006554dd6538feefb0;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

staging: comedi: ni_670x: remove spurious free_irq() call

This driver's comedi `detach` handler (`ni_670x_detach()`) calls
`free_irq()` but the driver doesn't call `request_irq()` anywhere.
Remove the spurious call.
