In preparation to enabling -Wimplicit-fallthrough, mark switch
cases where we are expecting to fall through.
This patch fixes the following warning:
drivers/ide/ide-floppy.c: In function ‘ide_floppy_get_capacity’:
drivers/ide/ide-floppy.c:424:7: warning: this statement may fall through [-Wimplicit-fallthrough=]
if (!(drive->atapi_flags & IDE_AFLAG_CLIK_DRIVE))
^
drivers/ide/ide-floppy.c:431:3: note: here
case CAPACITY_CURRENT:
^~~~
Warning level 3 was used: -Wimplicit-fallthrough=3
Notice that, in this particular case, the code comment is modified
in accordance with what GCC is expecting to find.
This patch is part of the ongoing efforts to enable
-Wimplicit-fallthrough.
