Staging: iio/accel: Changed return type of lis3l02dq_read_event_config() to int
The lis3l02dq_read_event_config() function returned an ssize_t up to
now, which lead to a compiler warning in line 660 (initialization from
incompatible pointer type). The iio_info struct is defined to accept an
int-returning function as the read_event_config parameter.
Also it seems odd to have the check for (ret < 0) and return ret in
this case, when the return type is signed.

Staging: iio/accel: Changed data type for val to unsigned long in write_frequency
In lis3102dq_write_frequency() we used a long variable to store the
value parsed from the char* buffer buf, as there only was a
strict_strtol() function to parse values.
Now we have got kstrto* which allows us to convert to the right data
type in most cases.
In this particular function we want to write a frequency value, and it
doesn't make sense to allow negative values here (as Dan Carpenter
pointed out in a previous email).
This means we can now parse the value into an unsigned long and get an
error for invalid (e.g. negative) values.

staging:iio: Add missing MODULE_DEVICE_TABLE and MODULE_ALIAS
Quite a few iio drivers provide no MODULE_DEVICE_TABLE or MODULE_ALIAS or only
provide a MODULE_ALIAS while they have support for multiple device ids. This
prevents auto module loading from working correctly.
This patch fixes it by adding the missing MODULE_DEVICE_TABLEs and
MODULE_ALIAS'.

staging:iio:treewide only use shared to decide on interfaces
Internally the fact that say scale is shared across channels is
actually of remarkably little interest. Hence lets not store it.
Numerous devices have weird combinations of channels sharing
scale anyway so it is not as though this was really telling
us much. Note however that we do still use the shared sysfs
attrs thus massively reducing the number of attrs in complex
drivers.
Side effect is that certain drivers that were abusing this
(mostly my work) needed to do a few more checks on what the
channel they are being queried on actually is.
This is also helpful for in kernel interfaces where we
just want to query the scale and don't care whether it
is shared with other channels or not.

staging:iio: Do not use bitmasks for channel info addresses
Currently the iio framework uses bitmasks for the address field of channel info

only ever query a single info attribute at once. This patch changes the code to
use the non-shifted iio_chan_info_enum values for the info attribute address.

staging:iio: header reorganization
Issue brought up by Lars-Peter Clausen. This is a varient of what
he suggested.
io/iio.h for driver stuff (has to include types.h)
Sub files for the bits drivers may or may not use
iio/sysfs.h
iio/buffer.h (contents of current buffer_generic.h)
(obviously anything offering events will need events.h as well)
iio/types.h for the enums that matter to both
iio_chan_type, iio_modifier
iio/events.h for the event code stuff
IIO_EVENT_CODE and friends. + everything in chrdev.h So this
is the stuff that userspace cares about.
Also include iio_event_type, iio_event_direction
Thus iio drivers include iio.h + as required
events.h
sysfs.h
buffer.h
in kernel users (once that interface is merged) will need inkern.h
which will pull in types.h
Userspace will need just events.h (which pulls in types.h) to get
everything they need to know about. Buffer userspace access doesn't
currently need any core defines. All information about the data
format is passed through sysfs.

staging: iio: lis3l02dq - incorrect ws used in container of call.
The word oops comes to mind. Original patch to merge the two work queues
in here (prior to Greg taking them into staging) changed the top half to
only use one of them and the bottom half to assume it was the other.
Currently causes a NULL pointer dereference if you enable any of the events
on an lis3l02dq. Just goes to show I need a few more regression tests.

include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h
percpu.h is included by sched.h and module.h and thus ends up being
included when building most .c files. percpu.h includes slab.h which
in turn includes gfp.h making everything defined by the two files
universally available and complicating inclusion dependencies.
percpu.h -> slab.h dependency is about to be removed. Prepare for
this change by updating users of gfp and slab facilities include those
headers directly instead of assuming availability. As this conversion
needs to touch large number of source files, the following script is
used as the basis of conversion.
http://userweb.kernel.org/~tj/misc/slabh-sweep.py
The script does the followings.
* Scan files for gfp and slab usages and update includes such that
only the necessary includes are there. ie. if only gfp is used,
gfp.h, if slab is used, slab.h.
* When the script inserts a new include, it looks at the include
blocks and try to put the new include such that its order conforms
to its surrounding. It's put in the include block which contains
core kernel includes, in the same order that the rest are ordered -
alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
doesn't seem to be any matching order.
* If the script can't find a place to put a new include (mostly
because the file doesn't have fitting include block), it prints out
an error message indicating which .h file needs to be added to the
file.
The conversion was done in the following steps.
1. The initial automatic conversion of all .c files updated slightly
over 4000 files, deleting around 700 includes and adding ~480 gfp.h
and ~3000 slab.h inclusions. The script emitted errors for ~400
files.
2. Each error was manually checked. Some didn't need the inclusion,
some needed manual addition while adding it to implementation .h or
embedding .c file was more appropriate for others. This step added
inclusions to around 150 files.
3. The script was run again and the output was compared to the edits
from #2 to make sure no file was left behind.
4. Several build tests were done and a couple of problems were fixed.
e.g. lib/decompress_*.c used malloc/free() wrappers around slab
APIs requiring slab.h to be added manually.
5. The script was run on all .h files but without automatically
editing them as sprinkling gfp.h and slab.h inclusions around .h
files could easily lead to inclusion dependency hell. Most gfp.h
inclusion directives were ignored as stuff from gfp.h was usually
wildly available and often used in preprocessor macros. Each
slab.h inclusion directive was examined and added manually as
necessary.
6. percpu.h was updated not to include slab.h.
7. Build test were done on the following configurations and failures
were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my
distributed build env didn't work with gcov compiles) and a few
more options had to be turned off depending on archs to make things
build (like ipr on powerpc/64 which failed due to missing writeq).
* x86 and x86_64 UP and SMP allmodconfig and a custom test config.
* powerpc and powerpc64 SMP allmodconfig
* sparc and sparc64 SMP allmodconfig
* ia64 SMP allmodconfig
* s390 SMP allmodconfig
* alpha SMP allmodconfig
* um on x86_64 SMP allmodconfig
8. percpu.h modifications were reverted so that it could be applied as
a separate patch and serve as bisection point.
Given the fact that I had only a couple of failures from tests on step
6, I'm fairly confident about the coverage of this conversion patch.
If there is a breakage, it's likely to be something in one of the arch
headers which should be easily discoverable easily on most builds of
the specific arch.

and ring buffer support.
This core patch provides an event interface and sysfs
based reading of values.
