|     ubiformat: fix the subpage size hint on the error path
|
|     David Binderman <dcb314@hotmail.com> reports that the following piece of looks
|     wrong:
|
|     if (!args.subpage_size != mtd->min_io_size)
|         normsg("may be sub-page size is incorrect?");
|
|     I totally agree with him and I believe that we actually meant to have no
|     negation in fron to f 'args.subpage_size', so instead, the code should look
|     like this:
|
|     if (args.subpage_size != mtd->min_io_size)
|         normsg("may be sub-page size is incorrect?");
