Hmm, but there are functional changes as noted above, I removed this line
from the patch description.

with IDEFLOPPY_DEBUG_LOG set to 1:

drivers/ide/ide-floppy.c: In function ‘idefloppy_pc_intr’:
drivers/ide/ide-floppy.c:704: warning: too many arguments for format
drivers/ide/ide-floppy.c: In function ‘idefloppy_do_request’:
drivers/ide/ide-floppy.c:1126: error: ‘struct request’ has no member named ‘flags’
make[1]: *** [drivers/ide/ide-floppy.o] Error 1
make: *** [drivers/ide/ide-floppy.o] Error 2

which translate to:

[...]

"%s: I/O error\n"

[...]

This was broken before this patch by rq->flags -> rq->cmd_type change
(so your patch is not to blame for breaking IDEFLOPPY_DEBUG_LOG ;).

I fixed the above issues while merging the patch.
