mtd: check parts pointer before using it

2011-09-11T12:02:18+00:00

The code has the check for parts but it called after kmemdup,
kmemdup(parts, sizeof(*parts) * nr_parts,...)
if (!parts)
	return -ENOMEM

In fact, we need check parts before safely using it.
and we also need check the real_parts to make sure kmemdup
allocation sucessfully.

mtd: replace DEBUG() with pr_debug()

2011-09-11T12:02:16+00:00

Start moving away from the MTD_DEBUG_LEVEL messages. The dynamic
debugging feature is a generic kernel feature that provides more
flexibility.

(See Documentation/dynamic-debug-howto.txt)

Also fix some punctuation, indentation, and capitalization that went
along with the affected lines.

mtd: drop mtd_device_register

2011-09-11T12:02:13+00:00

mtd_device_register() is a limited version of mtd_device_parse_register.
Replace it with macro calling mtd_device_parse_register().

mtd: abstract last MTD partition parser argument

2011-09-11T12:02:10+00:00

Encapsulate last MTD partition parser argument into a separate
structure. Currently it holds only 'origin' field for RedBoot parser,
but will be extended in future to contain at least device_node for OF
devices.

mtd: add new API for handling MTD registration

2011-09-11T12:02:05+00:00

Lots (nearly all) mtd drivers contain nearly the similar code that
calls parse_mtd_partitions, provides some platform-default values, if
parsing fails, and registers  mtd device.

This is an aim to provide single implementation of this scenario:
mtd_device_parse_register() which will handle all this parsing and
defaults.

These symbols are replaced with mtd_device_register() (and removal with
mtd_device_unregister()) for public registration.

mtd: introduce mtd_device_(un)register()

2011-05-25T01:12:36+00:00

To prepare for the removal of add_mtd_device and add_mtd_partitions(),
introduce mtd_device_register().  This will create partitions if they
are supplied or register the whole device if there are no partitions.

Once all drivers are converted to use mtd_device_register(),
add_mtd_device() and add_mtd_partitions() will be made internal only.

v2: move kerneldoc to implementation file and fixup some kerneldoc
warnings.

mtd: simplify get_mtd_device_nm function

2011-05-25T01:05:49+00:00

'get_mtd_device_nm()' has a piece of code which equivalent to what
'__get_mtd_device()' does - remove this duplicated code and use
''__get_mtd_device()' instead.
