mtd: spinand: fix NULL pointer dereference with no ECC engine
In the Linux kernel, the following vulnerability has been resolved: mtd: spinand: fix NULL pointer dereference with no ECC engine When "nand-no-ecc-engine" is set in DT, nanddev_get_ecc_engine() takes the NAND_ECC_ENGINE_TYPE_NONE path and returns success while leaving nand->ecc.engine NULL. The SPI-NAND code nevertheless dereferences it unconditionally to test for a pipelined engine, so probing such a device oopses immediately. Rather than open-coding the test three times, add a nand_ecc_is_pipelined() helper to the NAND core that folds the NULL check into the integration comparison, and use it everywhere. Future callers then cannot reintroduce the problem.
