Subject: [PATCH 3/3] Staging: comedi: removed "depricated" from COMEDI_CB_BLOCK

BugLink: http://bugs.launchpad.net/bugs/483343

The flag COMEDI_CB_BLOCK was marked as "depricated in the header file".
However, this flag is important to wake up the data-reader (and writer)
after new data has arrived from(for) the DAQ card.

(cherry picked from commit d103bef45180892515345e761f42db5601de9846 upstream)

Essentially a noop.
