From e88b1fc6a1c1d088824eb4869a70c374da9ebc86 Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Fri, 14 Nov 2014 16:49:49 -0800 Subject: [PATCH] Revert "misc: always assign miscdevice to file->private_data in open()" This reverts commit 32eca22180804f71b06b63fd29b72f58be8b3c47. Changing core kernel code to operate in a different manner, without a build-time breakage is tough to do and ensure you got it right. There are lots of problems popping up due to this change, so let's revert it for now as it is not safe to merge to the tree at this point in time.
