Greetings, Here is another bug exposed by patch commit bea5b158ff0da9c7246ff391f754f5f38e34577a Author: Rob Herring <robh(a)kernel.org&gt; AuthorDate: Thu Aug 11 10:20:58 2016 -0500 Commit: Greg Kroah-Hartman <gregkh(a)linuxfoundation.org&gt; CommitDate: Wed Aug 31 15:13:55 2016 +0200 driver core: add test of driver remove calls during probe In recent discussions on ksummit-discuss[1], it was suggested to do a sequence of probe, remove, probe for testing driver remove paths. This adds a kconfig option for said test. [1] https://lists.linuxfoundation.org/pipermail/ksummit-discuss/2016-August/0...
