* Add missing MODULE_DEVICE_TABLE() in tango_nand.c
* Update the number of corrected bitflips
core fixes:
* Fix a long standing memory leak in nand_scan_tail()
* Fix several bugs introduced by the per-vendor init/detection
infrastructure (introduced in 4.12)
* Add a static specifier to nand_ooblayout_lp_hamming_ops definition
