There must not be a new-line character in the uevent.  Otherwise, udev gets
confused.  Thanks to Kay Sievers for pointing it out.

Make the bay driver send env information on bay events.

Upon any bay event, we will send the string "BAY_EVENT=%d" along with the
KOBJ_CHANGE, and report the event number.  What the event number means will
be platform specific.  Event 3 is always an eject request, but an insert
may be either event 1, or it may be event 0.  Event 1 may also be a
remove request.  It would be best if you check the number of your event
with udevmonitor before writing any udev scripts for inserting and
removing drive bays.

Since platform devices seem to get uevents suppressed by default,
manually unsuppress for the bay device since we want to be able
to send uevents.

It was erroneously used as a description rather than a name.

ie. turn this:

lenb@se7525gp2:/sys> ls bus/acpi/drivers
ACPI AC Adapter Driver  ACPI Embedded Controller Driver  ACPI Power Resource Driver
ACPI Battery Driver     ACPI Fan Driver                  ACPI Processor Driver
ACPI Button Driver      ACPI PCI Interrupt Link Driver   ACPI Thermal Zone Driver
ACPI container driver   ACPI PCI Root Bridge Driver      hpet

into this:

Make "module name" actually match the file name.
Invoke with ';' as leaving it off confuses Lindent and gcc doesn't care.
Fix indentation where Lindent did get confused.

The bay driver is a platform driver, and doesn't need to also be an acpi
driver.  Remove the acpi driver related structures and callbacks, they didn't
do anything anyway.  Switch to uevent for user space event notification.
