Subject: [PATCH] drivers/input/evdev.c: Fix printf() format for sizeof

commit f2afa7711f8585ffc088ba538b9a510e0d5dca12 ("Input: paper over a bug in
Synaptics X driver") introduced a compiler warning on 64-bit platforms, as
sizeof() returns a size_t, not an (unsigned) int:

| drivers/input/evdev.c: In function 'handle_eviocgbit':
| drivers/input/evdev.c:684: warning: format '%d' expects type 'int', but argument 3 has type 'long unsigned int'

Use the proper `z' modifier for size_t, and make the printf() formats for the
sizes unsigned while we're at it.
