From 200d0177b4623cf218239ad7a21466459c174bff Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Tue, 3 Jan 2017 19:00:20 +0200 Subject: gpio: devres: Use global array of gpio suffixes We have already a global array of possible GPIO suffixes. Use it here instead of another copy of them. Unfortunately this will not reduce the memory footprint, though allows to easy maintain list in only one place.
