Subject: [PATCH] gpio: rcar: Use of_device_get_match_data() helper
Date: Wed,  4 Oct 2017 14:16:16 +0200	[thread overview]
Message-ID: <1507119376-12491-1-git-send-email-geert+renesas@glider.be> (raw)

Use the of_device_get_match_data() helper instead of open coding.
Note that the gpio-rcar driver is used with DT only, so there's always a
valid match.
