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.
