flash bbt broken due to unitialized bitflip_threshold?

Hi All,

nand_scan_tail calls chip->scan_bbt which in case of a flash based bbt
calls mtd_read. mtd_read returns -EUCLEAN when the number of errors
exceeds bitflip_threshold. The problem is that bitflip_threshold is
uninitialized at that time, it is initialized in add_mtd_device which is
called after nand_scan. This is seen on the mxc_nand controller, but
probably on other drivers aswell.

Am I missing something?
