Subject: gpio: tegra: Use platform_get_irq()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=9c07409c34ddf1804721cee21ca835733e165bde;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

gpio: tegra: Use platform_get_irq()

Instead of using platform_get_resource() and getting the interrupts from
the resource, use platform_get_irq() which is slightly easier to use and
covers some special cases that the former doesn't.
