Subject: [media] adv7180: Pass correct flags to request_threaded_irq()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=f3e991d418c7ee2890b1956c32f8b31639249ade;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

[media] adv7180: Pass correct flags to request_threaded_irq()

Most IRQ controllers support different types of interrupts. The adv7180
generates falling edge interrupts, so make sure to pass IRQF_TRIGGER_FALLING
to request_threaded_irq() so the IRQ controller is configured for the
correct mode.
