There was an error path that skipped the free_irq() step by mistake.

dmaengine: delete redundant chan_id and chancnt initialization in dma drivers

2011-09-20T06:21:33+00:00

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.

mfd: Use mfd cell platform_data for timberdale cells platform bits

2011-05-26T17:45:05+00:00

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.

mfd: mfd_cell is now implicitly available to timberdale drivers

2011-03-23T09:41:52+00:00

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.

drivers/dma: Eliminate a NULL pointer dereference

2010-07-01T09:27:35+00:00

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
//

kernel-wide: replace USHORT_MAX, SHORT_MAX and SHORT_MIN with USHRT_MAX, SHRT_MAX and SHRT_MIN

2010-05-25T15:07:02+00:00

- 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.

DMAENGINE: extend the control command to include an arg

2010-05-17T23:30:42+00:00

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.
