From cb71941a682270dd5164d1332900694d19caa5e1 Mon Sep 17 00:00:00 2001 From: David Daney Date: Tue, 22 May 2012 15:47:19 -0700 Subject: of/spi: Fix SPI module loading by using proper "spi:" modalias prefixes. To get modprobe to automatically load the proper modules, we need to prefix things with "spi:". Partially based on Grant Likely's suggestions.
