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(). This patch changes the type of return value of acpi_register_gsi() from "unsigned int" to "int" to indicate an error. If acpi_register_gsi() fails to register gsi, it returns negative value.
