Browse Source 
Add a kerneldoc comment for the 'parse_mtd_partitions()' function - its
behavior has changed recently so it is good idea to have it documented.

* This function tries to find partition on MTD device @master. It uses MTD
* partition parsers, specified in @types. However, if @types is %NULL, then
* the default list of parsers is used. The default list contains only the
* "cmdlinepart" parser ATM.
*
* This function may return:
* o a negative error code in case of failure
* o zero if no partitions were found
* o a positive number of found partitions, in which case on exit @pparts will
* point to an array containing this number of &struct mtd_info objects.
