[PATCH v2 00/60] Fix mtd parent device not showing up in sysfs

[Frans Klaver]

Here's the second iteration of 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. Again, if it's preferred that the patches are
grouped differently, 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.

Thanks for having a go at your favorite MTD,
Frans

v1..v2
  - Overall: make it more clear that it's about a parent device symlink gone
    missing (thanks, Brian)
  - Fix compile error in 30: "fsmc_nand: show parent device in sysfs"
  - Fix possible null-pointer dereference in 02: "mtd: core: set some
    defaults..."
