[PATCH 1/2] mtd: Annotate implicit fall through in nand_command/nand_command_lp

From: Mathieu Malaterre
Date: Wed Jan 16 2019 - 14:51:26 EST


There is a plan to build the kernel with -Wimplicit-fallthrough and
these places in the code produced warnings (W=1).

This commit removes the following warnings:

drivers/mtd/nand/raw/nand_legacy.c:332:6: warning: this statement may fall through [-Wimplicit-fallthrough=]
drivers/mtd/nand/raw/nand_legacy.c:483:3: warning: this statement may fall through [-Wimplicit-fallthrough=]
