[PATCH v2 00/18] staging: comedi: make core track the number of scans

[H Hartley Sweeten]

The comedi drivers that support async commands with a cmd->stop_src of TRIG_COUNT
currently have a private data member that is used to count the number of scans
completed in order to detect the end of acquisition for the command.

This series addes a new member, 'scans_done', to comedi_async and makes the core
automatically count the completed scans. The comedi drivers that do simple scan
counting are then converted to use the new member.

v2: update series per suggestions from Ian Abbott
    PATCH 01/18 - clamp scans_done to UINT_MAX
    PATCH 12/18 - clear devpriv->ai_cmd_running flag correctly
