    Subject[PATCH 091/190] Revert "pinctrl: axp209: Fix NULL pointer dereference after allocation"
    Date
    This reverts commit 1adc90c7395742827d754a5f02f446818a77c379.

    Commits from @umn.edu addresses have been found to be submitted in "bad
    faith" to try to test the kernel community's ability to review "known
    malicious" changes. The result of these submissions can be found in a
    paper published at the 42nd IEEE Symposium on Security and Privacy
    entitled, "Open Source Insecurity: Stealthily Introducing
    Vulnerabilities via Hypocrite Commits" written by Qiushi Wu (University
    of Minnesota) and Kangjie Lu (University of Minnesota).

    Because of this, all submissions from this group must be reverted from
    the kernel tree and will need to be re-reviewed again to determine if
    they actually are a valid fix. Until that work is complete, remove this
    change to ensure that no problems are being introduced into the
    codebase.
