The use of defined() on arrays and hashes has been deprecated since perl
5.6, but until 5.17.6 it only warned on lexicals, not package globals.

pcmcia: move unbind/rebind into dev_pm_ops.complete
Move the device rebind procedures for cardbus devices from the pm.resume
into the pm.complete callback.
The reason for moving the code is: "[...] The PM code needs to send
suspend and resume messages to every device in the right order, and it
can't do that if new devices are being added at the same time. [...]"
However the situation really isn't quite that rigid. In particular,
adding new children during a resume callback shouldn't cause much of
problem because the children don't need to be resumed anyway (since they
were never suspended). On the other hand, if you do it you will get a
dev_warn() from the PM core, something like 'parent should not be
sleeping'.
Still, it is considered bad form and should be avoided if possible."

acpi_memhotplug.c: auto bind the memory device which is hotplugged before the driver is loaded
If the memory device is hotplugged before the driver is loaded, the user
cannot see this device under the directory /sys/bus/acpi/devices/, and the
user cannot bind it by hand after the driver is loaded. This patch
introduces a new feature to bind such device when the driver is being
loaded.

We had introduced acpi_hotmem_initialized to avoid strange add_memory fail

device should be bound when the driver is being loaded. Remove
acpi_hotmem_initialized to allow that the device can be bound when the
