2014-03-10mtd: delete non-required instances of include <linux/init.h>Paul Gortmaker
None of these files are actually using any __init type directives and hence don't need to include <linux/init.h>. Most are just a left over from __devinit and __cpuinit removal, or simply due to code getting copied from one driver to the next.

2013-08-05mtd: nand: s3c2410: remove unnecessary platform_set_drvdata()Jingoo Han
The driver core clears the driver data to NULL after device_release or on probe failure, since commit 0998d0631001288a5974afc0b2a5f568bcdecb4d (device-core: Ensure drvdata = NULL when no driver is bound).

2012-03-27mtd: flash drivers set ecc strengthMike Dunn
Flash device drivers initialize 'ecc_strength' in struct mtd_info, which is the maximum number of bit errors that can be corrected in one writesize region. Drivers using the nand interface intitialize 'strength' in struct nand_ecc_ctrl, which is the maximum number of bit errors that can be corrected in one ecc step. Nand infrastructure code translates this to 'ecc_strength'. Also for nand drivers, the nand infrastructure code sets ecc.strength for ecc modes NAND_ECC_SOFT, NAND_ECC_SOFT_BCH, and NAND_ECC_NONE. It is set in the driver for all other modes.

2011-09-11mtd: nand: rename NAND_USE_FLASH_BBTBrian Norris
Recall the recently added prefix requirements: * "NAND_" for flags in nand.h, used in nand_chip.options * "NAND_BBT_" for flags in bbm.h, used in nand_chip.bbt_options or in nand_bbt_descr.options Thus, I am changing NAND_USE_FLASH_BBT to NAND_BBT_USE_FLASH. Again, this flag is found in bbm.h and so should NOT be used in the "nand_chip.options" field.

2011-09-11mtd: nand: consolidate redundant flash-based BBT flagsBrian Norris
This patch works with the following three flags from two headers (nand.h and bbm.h): (1) NAND_USE_FLASH_BBT (nand.h) (2) NAND_USE_FLASH_BBT_NO_OOB (nand.h) (3) NAND_BBT_NO_OOB (bbm.h) These flags are all related and interdependent, yet they were in different headers. Flag (2) is simply the combination of (1) and (3) and can be eliminated. This patch accomplishes the following: * eliminate NAND_USE_FLASH_BBT_NO_OOB (i.e., flag (2)) * move NAND_USE_FLASH_BBT (i.e., flag (1)) to bbm.h It's important to note that because (1) and (3) are now both found in bbm.h, they should NOT be used in the "nand_chip.options" field. I removed a small section from the mtdnand DocBook because it referes to NAND_USE_FLASH_BBT in nand.h, which has been moved to bbm.h.

As suggested by Andrew Morton, remove memzero() - it's not supported on other architectures so use of it is a potential build breaking bug.
