Remove unneeded error handling on the result of a call to
platform_get_resource when the value is passed to devm_ioremap_resource.
Move the call to platform_get_resource adjacent to the call to
devm_ioremap_resource to make the connection between them more clear.
A simplified version of the semantic patch that makes this change is as
follows: (http://coccinelle.lip6.fr/)
// <smpl>
@@
expression pdev,res,n,e,e1;
expression ret != 0;
identifier l;
@@
- res = platform_get_resource(pdev, IORESOURCE_MEM, n);
... when != res
- if (res == NULL) { ... \(goto l;\|return ret;\) }
... when != res
+ res = platform_get_resource(pdev, IORESOURCE_MEM, n);
e = devm_ioremap_resource(e1, res);
// </smpl>

The NX driver uses the transformation context to store several fields
containing data related to the state of the operations in progress.
Since a single tfm can be used by different kernel threads at the same
time, we need to protect the data stored into the context.
This patch makes use of spin locks to protect the data where a race
condition can happen.

This patch fixes a bug that is triggered when cts(cbc(aes)) is used with
nx-crypto driver on input larger than 32 bytes.
The chaining value from co-processor was not being saved. This value is
needed because it is used as the IV by cts(cbc(aes)).

Add support for OMAP4 version of TRNG module
that is present on OMAP4, AM33xx and OMAP5 SoCs.
The modules have several differences including register
offsets, output size, triggering rng and how configuring
FROs. To handle these differences, a platform_data structure
is defined and contains routine pointers, register offsets. OMAP2
specific routines are prefixed with 'omap2_' and OMAP4
specific routines are prefixed with 'omap4_'.
Note: Few Hard coded values are from the TI AM33xx SDK.

The co-processor has several limits regarding the length of
scatter/gather lists and the total number of bytes in it. These limits
are available in the device tree, as following:
- "ibm,max-sg-len": maximum number of bytes of each scatter/gather
list.
- "ibm,max-sync-cop": used for synchronous operations, it is an array
of structures that contains information regarding the limits that
must be considered for each mode and operation. The most important
limits in it are:
- The total number of bytes that a scatter/gather list can hold.
- The maximum number of elements that a scatter/gather list can
have.
This patch updates the NX driver to perform several hyper calls if
needed in order to always respect the length limits for scatter/gather
lists.

The co-processor receives data to be hashed through scatter/gather lists
pointing to physical addresses. When a vmalloc'ed data is given, the
driver must calculate the physical address to each page of the data.
However the current version of it just calculates the physical address
once and keeps incrementing it even when a page boundary is crossed.
This patch fixes this behaviour.

Add support for the OMAP5 version of the SHAM module
that is present on OMAP5 and AM43xx SoCs.
This module is very simialar to OMAP4 version of SHAM module,
and adds SHA384 SHA512 hardware-accelerated hash functions to it.
To handle the higher digest size of SHA512, few SHA512_DIGEST_i
(i=1-16, and first 8 registers are duplicated from SHA_DIGEST_i
registers) registers are added at the end of register set.
So adding the above register offsets and module info in pdata.

usable to emulate some optional FP instructions on processors with
hard FP that lack them (such as fsqrt on Freescale embedded
processors).

Ellerman. This facility allows what is basically "userspace

Intuos4 WL is separately reporting power supply and battery
charging status - now hid-wacom is using that information.
Previously hid-wacom was wrongly treating "battery charging" bit
as "power supply connected". Now it should report battery charging,
battery discharging, battery full and power supply status.
Intuos4 WL sends reports when is in use (obvious) and when unplugging
power supply. If means that if the device is being charged, but it's not
being used it will never report "battery full". The same problem happens
after the device has been connected, but it's not in use - the
battery/ac status will be incorrect. Currently there is no mechanism to
ask the device to send a report containing battery/ac status.

The current i2c hid driver does not support sending HID output reports using
the output register for devices which support receiving reports through this
method. This patch determines which method to use to send output reports based
on the value of wMaxOutputLength in the device's HID descriptor.

The recent comment:
commit 7e83ccbecd608b971f340e951c9e84cd0343002f
md/raid10: Allow skipping recovery when clean arrays are assembled
Causes raid10 to skip a recovery in certain cases where it is safe to
do so. Unfortunately it also causes a reshape to be skipped which is
never safe. The result is that an attempt to reshape a RAID10 will
appear to complete instantly, but no data will have been moves so the
array will now contain garbage.
(If nothing is written, you can recovery by simple performing the
reverse reshape which will also complete instantly).
Bug was introduced in 3.10, so this is suitable for 3.10-stable.

There is a bug in 'check_reshape' for raid5.c To checks
that the new minimum number of devices is large enough (which is
good), but it does so also after the reshape has started (bad).
This is bad because
- the calculation is now wrong as mddev->raid_disks has changed
already, and
- it is pointless because it is now too late to stop.
So only perform that test when reshape has not been committed to.

Power-up timing
The DS2408 is sensitive to the power-on slew rate and can inadvertently
power up with a test mode feature enabled. When this occurs, the P0 port
does not respond to the Channel Access Write command. For most reliable
operation, it is recommended to disable the test mode after every power-on
reset using the Disable Test Mode sequence shown below. The 64-bit ROM
code must be transmitted in the same bit sequence as with the Match ROM
command, i.e., least significant bit first. This precaution is
recommended in parasite power mode (VCC pin connected to GND) as well as
with VCC power.
Disable Test Mode:
