Casting the return value which is a void pointer is redundant.
The conversion from void pointer to any other pointer type is
guaranteed by the C programming language.

The driver core clears the driver data to NULL after device_release
or on probe failure, since commit 0998d06310
(device-core: Ensure drvdata = NULL when no driver is bound).
Thus, it is not needed to manually clear the device driver data to NULL.

The first 3 arguments of 'mtd_device_parse_register()' are pointers,
but many callers pass '0' instead of 'NULL'. Fix this globally. Thanks

mtd_device_parse_register() registers the device as a whole if no

Replace custom invocations of parse_mtd_partitions and mtd_device_register
with common mtd_device_parse_register call. This would bring: standard

Follow-on patch to the previous driver model patch for the MTD
framework. This one makes various MTD drivers connect to the
driver model tree, so /sys/devices/virtual/mtd/* nodes are no
longer present ... mostly drivers used on boards I have handy.
Based on a patch from Kay Sievers.

Once upon a time, the MTD repository was using CVS.
This patch therefore removes all usages of the no longer updated CVS

This also includes code that printed them to the user.

This enhances plat-ram to take a map_probes argument in
the platform_data structure which allow plat-ram to support
any direct-mapped device that MTD supports (jedec, cfi, amd ..)
A few items are also fixed:
- Don't panic if probes is 0
- Actually use the partition list that is passed in

Since 43cc71eed1, the platform modalias is
prefixed with "platform:". Add MODULE_ALIAS() to the hotpluggable MTD mapping
platform drivers, to re-enable auto loading.
NOTE oddness with physmap ... it's a legacy driver in some configs, which
means it can't always support hotplugging. (Not that most of these mapping
drivers would often be used as modules...)

I recently picked up my older work to remove unnecessary #includes of
sched.h, starting from a patch by Dave Jones to not include sched.h
from module.h. This reduces the number of indirect includes of sched.h
by ~300. Another ~400 pointless direct includes can be removed after
this disentangling (patch to follow later).
However, quite a few indirect includes need to be fixed up for this.
In order to feed the patches through -mm with as little disturbance as
possible, I've split out the fixes I accumulated up to now (complete for
i386 and x86_64, more archs to follow later) and post them before the real
patch. This way this large part of the patch is kept simple with only
adding #includes, and all hunks are independent of each other. So if any
hunk rejects or gets in the way of other patches, just drop it. My scripts
will pick it up again in the next round.
