    Subject[PATCH 4.4 28/29] clk: qcom: rcg: Return failure for RCG update
    Date
    From: Taniya Das <tdas@codeaurora.org>

    commit 21ea4b62e1f3dc258001a68da98c9663a9dbd6c7 upstream.

    In case of update config failure, return -EBUSY, so that consumers could
    handle the failure gracefully.
