From 6b4a2a427245fd357208ccf427891805354ef5b1 Mon Sep 17 00:00:00 2001 From: Alexandru Ardelean Date: Wed, 25 Aug 2021 10:01:25 +0300 Subject: [PATCH] gpio: viperboard: remove platform_set_drvdata() call in probe The platform_set_drvdata() call is only useful if we need to retrieve back the private information. Since the driver doesn't do that, it's not useful to have it. This change removes it. Also removing with this change is some logging about the failure to init the gpio chip data. There are other logging methods to view that this failed.
