Subject: mtd: rawnand: Rename nand_default_bbt() into nand_create_bbt()
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=44b07b921dea5ec997fb929ceaa82582a7415816;p=openwrt%2Fstaging%2Fblogic.git

mtd: rawnand: Rename nand_default_bbt() into nand_create_bbt()

Rename nand_default_bbt() into nand_create_bbt() and pass it a nand_chip
object to prepare removal of the chip->scan_bbt() hook.

We add a temporary nand_default_bbt() wrapper which will be dropped
after the removal of ->scan_bbt().
