mtd: check parts pointer before using it

2011-09-11T12:02:18Z

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()

2011-09-11T12:02:16Z

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

2011-09-11T12:02:13Z

mtd_device_register() is a limited version of mtd_device_parse_register. Replace it with macro calling mtd_device_parse_register(). Signed-off-by: Dmitry Eremin-Solenikov Signed-off-by: Artem Bityutskiy

mtd: abstract last MTD partition parser argument

2011-09-11T12:02:10Z

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

2011-09-11T12:02:05Z

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.

mtd: remove add_mtd_partitions, add_mtd_device and friends

2011-05-25T01:25:16Z

These symbols are replaced with mtd_device_register() (and removal with mtd_device_unregister()) for public registration. Signed-off-by: Jamie Iles Signed-off-by: Artem Bityutskiy Signed-off-by: David Woodhouse

mtd: introduce mtd_device_(un)register()

2011-05-25T01:12:36Z

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. Artem: tweak comments: remove junk tabs, use dots consistently. Signed-off-by: Jamie Iles Signed-off-by: Artem Bityutskiy Signed-off-by: David Woodhouse

mtd: simplify get_mtd_device_nm function

2011-05-25T01:05:49Z

'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. Artem: changed commit message.
