Hi,

Current acpi_register_gsi() function has no way to indicate errors to
its callers even though acpi_register_gsi() can fail to register gsi
because of some reasons (out of memory, lack of interrupt vectors,
incorrect BIOS, and so on). As a result, caller of acpi_register_gsi()
cannot handle the case that acpi_register_gsi() fails. I think failure
of acpi_register_gsi() should be handled properly.

This series of patches changes acpi_register_gsi() to return negative
value on error, and also changes callers of acpi_register_gsi() to
handle failure of acpi_register_gsi().

Thanks,
Kenji Kaneshige
