    Subject[PATCH v2 7/8] power: ab8500_fg: Remove deprecated create_singlethread_workqueue
    alloc_ordered_workqueue() with WQ_MEM_RECLAIM set replaces
    deprecated create_singlethread_workqueue(). This is the identity
    conversion.

    The workqueue "fg_wq" is used for running the FG algorithm periodically.
    It has been identity converted.

    It has multiple work items viz fg_periodic_work, fg_low_bat_work,
    fg_reinit_work, fg_work, fg_acc_cur_work and fg_check_hw_failure_work,
    which require execution ordering. Hence, a dedicated ordered workqueue
    has been used here.

    The WQ_MEM_RECLAIM flag has been set to guarantee forward progress under
    memory pressure.
