    Subject[PATCH 4.9 097/206] ath10k: use the right length of "background"
    Date
    4.9-stable review patch.  If anyone has any objections, please let me know.

    ------------------

    From: Nicolas Iooss <nicolas.iooss_linux@m4x.org>

    commit 31b239824ece321c09bdb8e61e1d14814eaba38b upstream.

    The word "background" contains 10 characters so the third argument of
    strncmp() need to be 10 in order to match this prefix correctly.
