From: Paul Burton Date: Sun, 13 Aug 2017 04:36:21 +0000 (-0700) Subject: irqchip: mips-gic: Remove gic_set_dual_edge() X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=c26ba670cdb84e0556436be7bf68a75a1d4f4d76;p=openwrt%2Fstaging%2Fblogic.git irqchip: mips-gic: Remove gic_set_dual_edge() Remove the gic_set_dual_edge() function in favour of using the new change_gic_dual() accessor function which provides equivalent functionality. This also allows us to remove the gic_update_bits() function which gic_set_dual_edge() was the last user of, along with the GIC_INTR_OFS() & GIC_INTR_BIT() macros.
