    Subject[PATCH 088/190] Revert "mmc_spi: add a status check for spi_sync_locked"
    Date
    This reverts commit 611025983b7976df0183390a63a2166411d177f1.

    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.
