From 4bc178608baec1723d9a6bb70cd3360a0a4edd21 Mon Sep 17 00:00:00 2001 From: Thierry Reding Date: Mon, 24 Jul 2017 16:55:07 +0200 Subject: [PATCH] gpio: tegra: Fix checkpatch warnings Fix a couple of checkpatch warnings, such as complaints about bare unsigned being used (instead of unsigned int) and missing blank lines after declarations.
