From 310cdfa0097a94d8cc3c0c314d64d6eb1cc69bf8 Mon Sep 17 00:00:00 2001 From: Andrey Smirnov Date: Mon, 7 Nov 2016 08:53:14 -0800 Subject: pinctrl-sx150x: Move some code out of sx150x_init_hw Move the code configuring explicit IRQ acking into a standalone function to declutter sx150x_init_hw a bit and make that code somewhat less repetitious.
