Thanks, splitting this out is nice actually. And thanks for looking up
the background on this oversight.

I'm not really sure what the actual effect of that omission would be;
the file won't be left dangling in sysfs (the device is removed
entirely), but I'm not sure if that'd trigger some kind of internal
kobject memory leak.

Anyway, looks good to me.

Side note: this patch series sort of massages the definition of this
"offset" file. Now, IIUC, subpartitions will have an "offset" file
relative to their parent partition, not the master flash device. I'm not
sure which way is expected.
