I can't find any documentation on what the stride config option does
in nvmem, but looking at the code it's only used for alignment checks
in nvmem core, so this patch should be ok. Still: I'm wondering if it
shouldn't depend on the size of the eeprom or if we shouldn't make the
chip you're using a special case.

@David: what is the chip you're using? Is it an at24mac402 by any
chance? Were you affected by the read problem we fixed recently[1][2]
in at24?

@Srinivas: any comments on that?
Stride is there to enforce address alignment. As long as there is no 
issue on addresses aligned to 1 byte on at24 I do not see any issue with 
the patch.

Thanks,
