Changeset 7fa897b91a ("ide: trivial sparse
annotations") created an IDE bootup regression on big-endian systems.
In drivers/ide/ide-iops.c, function ide_fixstring() we now have the
loop:
for (p = end ; p != s;)
be16_to_cpus((u16 *)(p -= 2));
which will never terminate on big-endian because in such
a configuration be16_to_cpus() evaluates to "do { } while (0)"
Therefore, always evaluate the arguments to nop endian transformation
operations.
