From 08497f22b15affcf08fb2d1173caa73e7ad54df7 Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski Date: Mon, 13 Mar 2017 21:07:26 +0200 Subject: [PATCH] watchdog: s3c2410: Minor code cleanup Cleanup the code from minor readability issues (no functional changes): 1. Fix checkpatch: ERROR: Do not include the paragraph about writing to the Free Software Foundation's mailing address. 2. Fix checkpatch: WARNING: quoted string split across lines 3. Fix chechpatch: WARNING: Prefer 'unsigned int' to bare use of 'unsigned' 4. Use 'dev' consistently in probe function instead of mixing dev with &pdev->dev.
