The SPI-NAND code nevertheless dereferences it\nunconditionally to test for a pipelined engine, so probing such a\ndevice oopses immediately.\n\nRather than open-coding the test three times, add a\nnand_ecc_is_pipelined() helper to the NAND core that folds the NULL\ncheck into the integration comparison, and use it everywhere. Future\ncallers then cannot reintroduce the problem.","state":0,"publishedAt":"2026-10-23T12:11:34.935+00:00","modifiedAt":"2026-10-23T12:11:34.935+00:00","affected":[{"ecosystem":"Vendor
