    SubjectRe: [PATCH v3] phy/qcom-qmp-combo: propagate correct return value at phy_power_on()

    Is this found via code inspection or because the phy is failing to power
    on sometimes? I ask because I'm looking at a DP bug on Trogdor with
    chromeos' v6.6 based kernel and wondering if this is related.

    Also, is the call to phy_power_on() going to be checked in
    the DP driver?

    $ git grep -n phy_power_on -- drivers/gpu/drm/msm/dp/
    drivers/gpu/drm/msm/dp/dp_ctrl.c:1453: phy_power_on(phy);
