mtd: maps: fix error return code of physmap_flash_remove()
When platform_get_drvdata() returns NULL to info, no error return code of physmap_flash_remove() is assigned. To fix this bug, err is assigned with -EINVAL in this case Fixes: 73566edf9b91 ("[MTD] Convert physmap to platform driver") Reported-by: TOTE Robot <oslab@tsinghua.edu.cn> Signed-off-by: Jia-Ju Bai <baijiaju1990@gmail.com> Signed-off-by: Miquel Raynal <miquel.raynal@bootlin.com> Link: https://lore.kernel.org/linux-mtd/20210308034446.3052-1-baijiaju1990@gmail.com
