From 226cff485c803ac0f3a6bc52b9b638eb2c41181c Mon Sep 17 00:00:00 2001 From: Thierry Reding Date: Wed, 23 Aug 2017 11:25:08 +0200 Subject: [PATCH] soc/tegra: Restrict SoC device registration to Tegra Commit 8a46828e623c ("soc/tegra: Register SoC device") added an initcall to register the SoC device on Tegra. However, that code is unrestricted and will run on all platforms, causing unwanted warnings. Fix this by first checking that we're running on hardware that supports the fuses block that we use to provide SoC information.
