dma_async_device_register will re-init chan_id and chancnt,
so whatever chan_id and chancnt are set in drivers, they will
be re-written by dma_async_device_register.Cc: Nicolas Ferre

With the addition of a device platform mfd_cell pointer, MFD drivers
can go back to passing platform data back to their sub drivers.
This allows for an mfd_cell->mfd_data removal and thus keep the
sub drivers MFD agnostic. This is mostly needed for non MFD aware
sub drivers.Acked-by: Richard Röjfors

The cell's platform_data is now accessed with a helper function;
change clients to use that, and remove the now-unused data_size.Note that the mfd's platform_data is marked __devinitdata. This
is still correct in all cases except for the timbgpio driver, whose
remove hook has been changed to no longer reference the pdata.Signed-off-by: Andres Salomon

If td_desc is NULL, just skip both kfrees.
A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)//
@r exists@
expression E,E1;
identifier f;
statement S1,S2,S3;
@@if ((E == NULL && ...) || ...)
{
... when != if (...) S1 else S2
when != E = E1
* E->f
... when any
return ...;
}
else S3

- C99 knows about USHRT_MAX/SHRT_MAX/SHRT_MIN, not
USHORT_MAX/SHORT_MAX/SHORT_MIN.- Make SHRT_MIN of type s16, not int, for consistency.

This adds an argument to the DMAengine control function, so that
we can later provide control commands that need some external data
passed in through an argument akin to the ioctl() operation
prototype.[dan.j.williams@intel.com: fix up some missed conversions]

Convert the device_terminate_all() operation on the
DMA engine to a generic device_control() operation
which can now optionally support also pausing and
resuming DMA on a certain channel. Implemented for the
COH 901 318 DMAC as an example.[dan.j.williams@intel.com: update for timberdale]
