parport: ieee1284: mark expected switch fall-through
In preparation to enabling -Wimplicit-fallthrough, mark switch cases where we are expecting to fall through. This patch fixes the following warning: drivers/parport/ieee1284.c: In function ‘parport_read’: drivers/parport/ieee1284.c:722:6: warning: this statement may fall through [-Wimplicit-fallthrough=] if (parport_negotiate (port, IEEE1284_MODE_NIBBLE)) { ^ drivers/parport/ieee1284.c:726:2: note: here case IEEE1284_MODE_NIBBLE: ^~~~ 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. Signed-off-by: Gustavo A. R.
