keep the hex error value reporting version (a) to be consistent
with decrypt_done(), and (b) to keep our hardware guys happy.

remains from descriptor debugging - not required for normal operation.

The presence of a h/w Queue Interface would fail due to this
cut-n-paste snafu.

- add IRQF_SHARED to request_irq flags to support parts such as
the p1023 that has one IRQ line per couple of rings.
- resetting a job ring triggers an interrupt, so move request_irq
prior to jr_reset to avoid 'got IRQ but nobody cared' messages.
- disable IRQs in h/w to avoid contention between reset and
interrupt status
- delete invalid comment - if there were incomplete jobs,
module would be in use, preventing an unload.

Error handling code following a kmalloc should free the allocated data.
The semantic match that finds the problem is as follows:
(http://www.emn.fr/x-info/coccinelle/)
// <smpl>
@r exists@
local idexpression x;
statement S;
expression E;
identifier f,f1,l;
position p1,p2;
expression *ptr != NULL;
@@
x@p1 = \(kmalloc\|kzalloc\|kcalloc\)(...);
...
if (x == NULL) S
<... when != x
when != if (...) { <+...x...+> }
(

(x->f1 == NULL || ...)

ARRAY_SIZE() was intended here instead of sizeof(). sizeof() is four
times larger than ARRAY_SIZE(). outstr is normally 256 chars so
printing garbage to it could overfill the buffer and corrupt memory.

t_alg is an ERR_PTR here so we can't dereference it.

Help clarify that the number trailing in compatible nomenclature
is the version number of the device, i.e., change:
"fsl,p4080-sec4.0", "fsl,sec4.0";
to:
"fsl,p4080-sec-v4.0", "fsl,sec-v4.0";

The SEC4 supercedes the SEC2.x/3.x as Freescale's
Integrated Security Engine. Its programming model is
incompatible with all prior versions of the SEC (talitos).
The SEC4 is also known as the Cryptographic Accelerator
and Assurance Module (CAAM); this driver is named caam.
This initial submission does not include support for Data Path
mode operation - AEAD descriptors are submitted via the job
ring interface, while the Queue Interface (QI) is enabled
for use by others. Only AEAD algorithms are implemented
at this time, for use with IPsec.
Many thanks to the Freescale STC team for their contributions
to this driver.
