Miquel Raynal 26d13e9253 mtd: nand: fix interpretation of NAND_CMD_NONE in nand_command[_lp]() ... [ Upstream commit df467899da ] Some drivers (like nand_hynix.c) call ->cmdfunc() with NAND_CMD_NONE and a column address and expect the controller to only send address cycles. Right now, the default ->cmdfunc() implementations provided by the core do not filter out the command cycle in this case and forwards the request to the controller driver through the ->cmd_ctrl() method. The thing is, NAND controller drivers can get this wrong and send a command cycle with a NAND_CMD_NONE opcode and since NAND_CMD_NONE is -1, and the command field is usually casted to an u8, we end up sending the 0xFF command which is actually a RESET operation. Add conditions in nand_command[_lp]() functions to sending the initial command cycle when command == NAND_CMD_NONE.
