This addresses the Samsung P30 issue, where the INIT method would return no object, but the implicit return in the AML interpreter would confuse the driver. It also accounts for a newer batch of Asus models whose INIT returns ACPI_TYPE_BUFFER instead of STRING. The handling is now much leaner, if we get a buffer or a string, we check against known values, in every other case we use a different path (currently DSDT signatures). The bulk of this patch is separating the string matching from asus_hotk_get_info() into a separate function. This patch properly fixes http://bugme.osdl.org/show_bug.cgi?id=5067 and http://bugme.osdl.org/show_bug.cgi?id=5092 and makes the driver fully functional again with acpi=strict on all machines.
