Hi, Thanks for the patch.

But it doesn't compile against acpi4asus tree ( at http://git.iksaif.net/ ).

drivers/platform/x86/eeepc-laptop.c: In function
‘eeepc_setup_pci_hotplug’:
drivers/platform/x86/eeepc-laptop.c:743: error: ‘EEEPC_ERR’ undeclared
(first use in this function)
drivers/platform/x86/eeepc-laptop.c:743: error: (Each undeclared
identifier is reported only once
drivers/platform/x86/eeepc-laptop.c:743: error: for each function it
appears in.)
drivers/platform/x86/eeepc-laptop.c:743: error: expected ‘)’ before
string constant
drivers/platform/x86/eeepc-laptop.c:743: warning: format not a string

drivers/platform/x86/eeepc-laptop.c:764: warning: format not a string

I think it's because you use a tree without commit
3a49ed57e6fab16eae8b60afdd05c783ac155fd9 .
