2015-10-13mtd: core: set some defaults when dev.parent is setFrans Klaver1-0/+9
If a parent device is set, add_mtd_device() has enough knowledge to fill in some sane default values for the module name and owner. Do so if they aren't already set. Signed-off-by: Frans Klaver <[email protected]> Signed-off-by: Brian Norris <[email protected]>
2015-10-13mtd: core: tone down suggestion that dev.parent should be setFrans Klaver1-1/+1
add_mtd_device() has a comment suggesting that the caller should have set dev.parent. This is required to have the parent device symlink show up in sysfs, but not for proper operation of the mtd device itself. Currently we have five drivers registering mtd devices during module initialization, so they don't actually provide a parent device to link to. That means we cannot WARN_ON() here, as it would trigger false positives. Make the comment a bit less firm in its assertion that dev.parent should be set.

2015-10-12mtd: brcmnand: Fix pointer type-cast in brcmnand_write()Anup Patel1-2/+2
We should always type-cast pointer to "long" or "unsigned long" because size of pointer is same as machine word size. This will avoid pointer type-cast issues on both 32bit and 64bit systems.

2015-10-11mtd: nand_bbt: set the smallest size of bbt tableSheng Yong1-1/+1
When using nandsim to simulate a 128K block nand with `overridesize = 1', the size of mtd device is too small (mtd_size = 4 * block_size) to get the right length of bbt. Then when creating bbt, kzmalloc() will return ZERO_SIZE_PTR. This causes a NULL pointer oops when scanning bbt.
