3.10-stable review patch. If anyone has any objections, please let me know. ------------------ From: Stanislaw Gruszka <sgruszka@xxxxxxxxxx> commit 7b320cb1ed2dbd2c5f2a778197baf76fd6bf545a upstream. We have few fedora bug reports about list corruption on pinctrl, for example: https://bugzilla.redhat.com/show_bug.cgi?id=1051918 Most likely corruption happen due lack of protection of pinctrl_list when adding new nodes to it. Patch corrects that.
