Subject[PATCH 06/37] staging: comedi: add CMDF_WAKE_EOS as synonym for TRIG_WAKE_EOS
Date
`TRIG_WAKE_EOS` is one of the values that can be OR-ed into the `flags`
member of `struct comedi_cmd`. It's intended action is tune the
asynchronous command to interrupt at the end of every "scan". The name
is a bit of a left-over from earlier times. A better name would be
`CMDF_WAKE_EOS` to match various other command flags.

Define `CMDF_WAKE_EOS` with the same numeric value as the old
`TRIG_WAKE_EOS` and redefine `TRIG_WAKE_EOS` as a synonym of it.
