Merge tag 'nand/fixes-for-4.12-rc3' of git://git.infradead.org/linux-mtd into MTD
From Boris: """ This pull request contains several fixes to the core and the tango driver. tango fixes: * 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 """
