In fact this is not done by most nand drivers. What follows is a series which fixes this. Tested: orion and omap2 Compile-Tested: atmel, gpio, fsmc, gpmi, plat, pxa3xx, s3c2410, sh_flctl, sharpsl, tmio, docg4, davinci, lpc32xx_mlc, lpc32xx_slc, mxc Not tested at all (only be view, patches 19-27): bcm47, fsl_elbc, fsl_upm, fsl_ifc, jz4740, mpc5121m, ndfc, txx9ndfmx, socrates The overall stat is 27 files changed, 36 insertions(+), 80 deletions(-) and it fixes 21 of these bugs.
