Subject: of/irq: Replace of_irq with of_phandle_args
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=530210c7814e83564c7ca7bca8192515042c0b63;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

of/irq: Replace of_irq with of_phandle_args

struct of_irq and struct of_phandle_args are exactly the same structure.
This patch makes the kernel use of_phandle_args everywhere. This in
itself isn't a big deal, but it makes some follow-on patches simpler.
