Subject: irqchip: mips-gic: Remove gic_set_trigger()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=471aa962a6acc19a990e20fa3846db40e62120cc;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

irqchip: mips-gic: Remove gic_set_trigger()

Remove the gic_set_trigger() function in favour of using the new
change_gic_trig() accessor function which provides equivalent
functionality.
