One of the legit warnings 'make W=3 drivers/ide/ide-cd.o generates is

drivers/ide/ide-cd.c: In function ide_cd_queue_pc:
drivers/ide/ide-cd.c:451:3: warning: conversion to unsigned int from
      int may change the sign of the result

timeout is passed as an int, but is declared as an unsigned int in
struct request in include/linux/blkdev.h

This is beyond academic and may in fact introduce strange things.

All except one call site passes "0" for the timeout.

And that one call site passes packet_command->timeout from userspace
which is an 'int'.

I'm not applying this.
