[PATCH 00/60] Fix mtds not showing up in sysfs

Hi there,

Here's a series stemming from a previous discussion about mtd devices not
showing up in sysfs properly[1]. While the original series 27 patches, this one
should cover all drivers that suffer from this issue, and shamelessly hits 60.
If it's preferred that the patches be more logically grouped, like by mtd
subdir, I'd be happy to resend. Until then, we'll make do with this.

This series teaches add_mtd_device() to set name and owner based on the set
parent device, if dev.parent is filled in, and name resp. owner isn't already
filled in. All drivers that I could find that don't set the parent are touched
to set the parent device, and remove the name and owner assignment in cases
where I'm sure the resulting name will not change. Only the latter is done in
cases where I would find the driver explicitly filling in the owner.

I was able to actually test nand/omap2. Compile tested are:
  devices/docg3
  devices/m25p80
  devices/mtd_dataflash
  devices/sst251
  lpddr/lpddr2_nvm
  maps/gpio-addr-flash
  maps/intel_vr_nor
  maps/latch-addr-flash
  maps/physmap
  maps/physmap_of
  maps/plat-ram
  nand/cafe_nand
  nand/denali
  nand/docg4
  nand/gpio
  nand/plat_nand
  onenand/generic

The rest is untested. If you have suggestions for me to compile-test most of
them for a next run, I'd be much obliged.

Thanks for having a go at your favorite MTD,
Frans
