[PATCH 6/8] bind the memory device when the driver is being loaded

From: Wen Congyang
Date: Tue Jun 26 2012 - 05:17:26 EST


We introduce acpi_hotmem_initialized to avoid strange add_memory fail message.
The stranged add_memory fail message is printed in register_memory_resource().
We have removed this message in the previous patch, so we can remove
it(it is very useful to the next patch).
