From 9dd1a30cb4881328ae568f6c060446b52539a2dd Mon Sep 17 00:00:00 2001 From: Vladimir Zapolskiy Date: Thu, 29 Nov 2018 00:28:47 +0200 Subject: gpio: lpc18xx: add struct device local variable This is a non-functional change, it simplifies multiple access to 'struct device' pointer derived from a platform device pointer, the new local variable will also be used in the following changes.
