A report from Colin Ian King pointed a CoverityScan issue where error values on these helpers where not checked in the drivers. These helpers can error out only in case of a software bug in driver code, not because of a runtime/hardware error. Hence, let's WARN_ON() in this case and return 0 which is harmless anyway.
Fixes: 8878b126df76 ("mtd: nand: add ->exec_op() implementation") Cc: stable@vger.kernel.org
Is it really worth backporting this patch? I mean, the bug does not exist, it's just a potential problem that can only arise when drivers/core are buggy, which AFAICT is not the case yet :-).
Ok, I'll remove the Cc: stable tag but I guess I can keep the Fixes one.
