[PATCH] mtd: onenand_base: Mark expected switch fall-through

From: Gustavo A. R. Silva
Date: Tue Jun 04 2019 - 10:21:42 EST


In preparation to enabling -Wimplicit-fallthrough, mark switch cases
where we are expecting to fall through.

This patch fixes the following warning:

drivers/mtd/nand/onenand/onenand_base.c: In function âonenand_check_featuresâ:
drivers/mtd/nand/onenand/onenand_base.c:3264:17: warning: this statement may fall through [-Wimplicit-fallthrough=]
this->options |= ONENAND_HAS_NOP_1;
drivers/mtd/nand/onenand/onenand_base.c:3265:2: note: here
case ONENAND_DEVICE_DENSITY_4Gb:
^~~~

Warning level 3 was used: -Wimplicit-fallthrough=3

This patch is part of the ongoing efforts to enable
-Wimplicit-fallthrough.
