mtd: rawnand: Use kzalloc() instead of kmalloc() and memset()
Replace kmalloc() by a memset() followed with a kzalloc(). There is a recommendation to use zeroing allocator rather than allocator followed by memset(0) in ./scripts/coccinelle/api/alloc/zalloc-simple.cocci Signed-off-by: Fuqian Huang <huangfq.daxian@gmail.com> Signed-off-by: Miquel Raynal <miquel.raynal@bootlin.com>
