    Subject[PATCH] dmaengine/amba-pl08x : reset phychan_hold on terminate all
    Date
    From: Davide Ciminaghi <ciminaghi@gnudd.com>

    When a client calls pl08x_control with DMA_TERMINATE_ALL, it is correct
    to terminate and release the phy channel currently in use (if one is in use),
    but the phychan_hold counter must also be reset (otherwise it could get
    trapped in an unbalanced state).
