device_driver'
This patch fixes the bug reported in
http://bugzilla.kernel.org/show_bug.cgi?id=11681.
"Lots of device drivers register a 'struct device_driver' with
the '.bus' member set to '&platform_bus_type'. This is wrong,
since the platform_bus functions expect the 'struct device_driver'
to be wrapped up in a 'struct platform_driver' which provides
some additional callbacks (like suspend_late, resume_early).
The effect may be that platform_suspend_late() uses bogus data
outside the device_driver struct as a pointer pointer to the
device driver's suspend_late() function or other hard to
reproduce failures."(Lothar Wassmann)

* Pass pointer to buffer for IDENTIFY data to do_identify()
and try_to_identify().
* Un-static try_to_identify() and use it in ide_driveid_update().
* Rename try_to_identify() to ide_dev_read_id().

do_identify() marks EXABYTENEST device as non-present and frees
drive->id so enable_nest() has absolutely no chance of working.
The code was like this since at least 2.6.12-rc2 and nobody
has noticed so just remove broken EXABYTENEST support.

* Doing kmalloc() in the middle of command execution is not only ugly
but leaves drive waiting to send data on kmalloc() failure. Fix it.
While at it:
* Unify error code paths.
* Fixup error message to be more useful and add missing KERN_ERR level.
* Rename 'stat' variable to 's'.

* Return 0 instead of dev->irq in ->init_chipset implementations.
* Fix ->init_chipset method to return 'int' value instead of
'unsigned int' one.
This fixes ->init_chipset handling for host drivers (cs5530, hpt366
and pdc202xx_new) for which it is possible for this method to fail.
