    Subject[PATCH 5.10 153/215] drm/vc4: txp: Properly set the possible_crtcs mask
    Date
    From: Maxime Ripard <maxime@cerno.tech>

    commit bf6de8e61509f3c957d7f75f017b18d40a18a950 upstream.

    The current code does a binary OR on the possible_crtcs variable of the
    TXP encoder, while we want to set it to that value instead.

    Cc: <stable@vger.kernel.org> # v5.9+
    Fixes: 39fcb2808376 ("drm/vc4: txp: Turn the TXP into a CRTC of its own")
