If we define dev_dbg(), then there is a possible NULL pointer
dereference.

Julia Lawall 17bebdcd5c crypto: bfin_crc - reposition free_irq to avoid access to invalid data
The data referenced by an interrupt handler should not be freed before the
interrupt is ended.  The handler is bfin_crypto_crc_handler.  It may refer
to crc->regs, which is released by the iounmap.

Furthermore, the second argument to all calls to free_irq is incorrect.  It
should be the same as the last argument of request_irq, which is crc,
rather than crc->dev.

The semantic match that finds the first problem is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>
@fn exists@
expression list es;
expression a,b;
identifier f;
@@

if (...) {
  ... when any
  free_irq(a,b);
  ... when any
  f(es);
  ... when any
  return ...;
}

@@
expression list fn.es;
expression fn.a,fn.b;
identifier fn.f;
@@

*f(es);
... when any
*free_irq(a,b);
// </smpl>

Greg Kroah-Hartman 49cfe4db2d Drivers: crypto: remove __dev* attributes.
CONFIG_HOTPLUG is going away as an option.  As a result, the __dev*
markings need to be removed.

This change removes the use of __devinit, __devexit_p, __devinitdata,
and __devexit from these drivers.

Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

Sonic Zhang b8840098b7 crypto: bfin_crc - CRC hardware driver for BF60x family processors.
The CRC peripheral is a hardware block used to compute the CRC of the block
of data. This is based on a CRC32 engine which computes the CRC value of 32b
data words presented to it. For data words of < 32b in size, this driver
pack 0 automatically into 32b data units. This driver implements the async
hash crypto framework API.
