One of the legit warnings 'make W=3 drivers/ide/ide-cd.o generates is
drivers/ide/ide-cd.c: In function .ide_cdrom_prep_fs.:
drivers/ide/ide-cd.c:1314: warning: conversion to .unsigned int. from .int. may change the sign of the result
because queue_logical_block_size() returns unsigned short but hard_sect
is defined as int. Fix that no matter how low the potential for this
becoming a bug is.
