I used this driver as a template for a custom one. While hacking on my own, I
noticed some problems in this driver, too. This series fixes the first set of
them, related to the "rom-size" parameter. It fixes a segfault.

I think the first patch is clearly suitable for stable. I think the second one,
too, but not as clearly. The third one is a cleanup and not for stable. Still,
I am open for opinions about these thoughts.

Thanks,

This is the same v3 as last time. Rebased to current master, but that produced
no diff.

Changes since v2:

* removed '\n' from error_report-strings
* made sure checkpatch is happy
* added tags from Philippe (thanks!)

Changes since v1:

* reordered patches according to significance for stable
* use AT24C_ROMSIZE_DEFAULT instead of magic value
* patch 3 doesn't improve the ERR macro anymore but replaces
  it completely with error_report().


Wolfram Sang (3):
  nvram: at24c: prevent segfault by checking "rom-size"
  nvram: at24c: use a sane default for "rom-size"
  nvram: at24c: use standard error reporting
