Subject: staging: comedi: me4000: use comedi_handle_events()
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=3fa1eb64d6d670676946ccd42d48452aecb96c2d;p=openwrt%2Fstaging%2Fblogic.git

staging: comedi: me4000: use comedi_handle_events()

Use comedi_handle_events() to automatically (*cancel) the async command
for an end-of-acquisition or if an error/overflow occurs.

Also, comedi_handle_events() does nothing if no events are set so the
check can be removed.
