From 32388d6ef7cffc7d8291b67f8dfa26acd45217fd Mon Sep 17 00:00:00 2001 From: Sakari Ailus Date: Wed, 10 Oct 2018 04:01:05 -0400 Subject: media: ipu3-cio2: Unregister device nodes first, then release resources While there are issues related to object lifetime management, unregister the media device first, followed immediately by other device nodes when the driver is being unbound. Only then the resources needed by the driver may be released. This is slightly safer.
