From 135d9f7d135a11ff4a5279325b06c5e8c82952b5 Mon Sep 17 00:00:00 2001 From: Jaewon Kim Date: Fri, 5 Jun 2015 13:32:27 +0900 Subject: [PATCH] extcon: max77843: Clear IRQ bits state before request IRQ IRQ signal before driver probe is needless because driver sends current state after platform booting done. So, this patch clears MUIC IRQ bits before request IRQ.
