Zhihao Cheng b9b89da56a mtd: mtdconcat: Check _read, _write callbacks existence before assignment ... [ Upstream commit a89d69a44e ] Since 2431c4f5b4 ("mtd: Implement mtd_{read,write}() as wrappers around mtd_{read,write}_oob()") don't allow _write|_read and _write_oob|_read_oob existing at the same time, we should check the existence of callbacks "_read and _write" from subdev's master device (We can trust master device since it has been registered) before assigning, otherwise following warning occurs while making concatenated device: WARNING: CPU: 2 PID: 6728 at drivers/mtd/mtdcore.c:595 add_mtd_device+0x7f/0x7b0 Fixes: 2431c4f5b4 ("mtd: Implement mtd_{read,write}() around ...")
