Subject: [PATCH 00/27] Fix common bug in most nand drivers not showing a device in sysfs


A comment in mtdcore.c function add_mtd_device() which is called by
mtd_device_parse_register() made me wonder:

"Caller should have set dev.parent to match the physical device."

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.

Regards,

Alexander Holler
