Variax driver had a very complex and staged startup sequence using
multiple timers and a work. This patch simplifies the procedure to a
single delayed work.
Now the startup stage consists of:
- VARIAX_STARTUP_VERSIONREQ:
requesting the version and the message handler raises up to the next
stage upon receiving the reply. The request is repeated until a
reply arrives.
- VARIAX_STARTUP_ACTIVATE:
does activation, and queue for the next stage.
- VARIAX_STARTUP_SETUP:
registers the card.

The POD driver had a complex staged startup procedure using both timer

requesting the version information and the process_message callback
triggers the next stage,
- POD_STARTUP_SETUP:
registering the actual card object.

The current code performs the cancel of a delayed work at the late
stage of disconnection procedure, which may lead to the access to the
already cleared state.
This patch assures to call cancel_delayed_work_sync() at the beginning
of the disconnection procedure for avoiding that race. The delayed
work object is now assigned in the common line6 object instead of its
derivative, so that we can call cancel_delayed_work_sync().
Along with the change, the startup function is called via the new
callback instead. This will make it easier to port other LINE6
drivers to use the delayed work for startup in later patches.

By taking into account the mapping from logical to DMA channels when
enabling or disabling audio channels, ADAT channels 3 to 8 on the RME
HDSPe AIO card are now correctly captured and played back in single speed
mode.
Since the mapping is an identity mapping for all cards except AIO and
RayDAT, only those cards should be affected by this patch. It was tested on
an AIO card. The patch needs testing on other cards, in particular RayDAT.
Note: this patch does not solve ADAT capture and playback issues in double

So, replace the following form:
