Return value of mtdtest_scan_for_bad_() is always 0. So it causes senseless
checks in some functions such as mtd_subpagetest_init().
Fixes: 084db4b020c7 ("mtd: tests: introduce helper functions")

What's the point of keeping "err =" or even keeping a return value if
void would be more appropriate?

Your function name got cut off.

Then maybe it should return void?

That's not mtdtest_scan_for_bad_eraseblocks().
