mtd: phram: Mark expected switch fall-throughs
In preparation to enabling -Wimplicit-fallthrough, mark switch cases where we are expecting to fall through. This patch fixes the following warnings: drivers/mtd/devices/phram.c: In function ‘parse_num64’: drivers/mtd/devices/phram.c:149:11: warning: this statement may fall through [-Wimplicit-fallthrough=] shift += 10; ~~~~~~^~~~~ drivers/mtd/devices/phram.c:150:4: note: here case 'M': ^~~~ drivers/mtd/devices/phram.c:151:11: warning: this statement may fall through [-Wimplicit-fallthrough=] shift += 10; ~~~~~~^~~~~ drivers/mtd/devices/phram.c:152:4: note: here case 'k': ^~~~ Warning level 3 was used: -Wimplicit-fallthrough=3 This patch is part of the ongoing efforts to enabling -Wimplicit-fallthrough.
