From 6d58954bafd97a3e3a99250cd8471e45521c0023 Mon Sep 17 00:00:00 2001 From: Wolfram Sang Date: Mon, 6 Jun 2016 18:48:38 +0200 Subject: [PATCH] of: fix autoloading due to broken modalias with no 'compatible' commit b3c0a4dab7e35a9b6d69c0415641d2280fdefb2b upstream. Because of an improper dereference, a stray 'C' character was output to the modalias when no 'compatible' was specified. This is the case for some old PowerMac drivers which only set the 'name' property. Fix it to let them match again.
