Fix a bug where mtd parent device symlinks aren't shown in sysfs. While at it, make use of the default owner value set by mtdcore. Incidentally, it seems the owner field in the concatenated mtds is not actually used, so this shouldn't make much of a difference anyway. Signed-off-by:

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 authored
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. Signed-off-by:

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. This patch fixes pointer type-cast issue in brcmnand_write() as-per above info. Signed-off-by:

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.

The probe of a mtd device can fail when a partition parser returns error. The failure due to partition parsing can be quite mysterious when multiple partitioning schemes are compiled in and any of them can fail the probe. Add debug prints which show what parsers were tried and what they returned. Signed-off-by:

According to LPC32xx User's Manual all values measured in clock cycles are programmable from 1 to 16 clocks (4 bits) starting from 0 in bitfield, the current version of calculated clock cycles is too conservative. Correctness of 0 bitfield value (i.e. programmed 1 clock timing) is proven with actual NAND chip devices. Signed-off-by:
