    Subject[PATCH 4.14 114/246] spi: Add missing pm_runtime_put_noidle() after failed get
    Date
    4.14-stable review patch.  If anyone has any objections, please let me know.

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

    From: Tony Lindgren <tony@atomide.com>

    [ Upstream commit 7e48e23a1f4a50f93ac1073f1326e0a73829b631 ]

    If pm_runtime_get_sync() fails we should call pm_runtime_put_noidle().
    This is probably not a critical fix as we should only hit this when
    things are broken elsewhere.
