ACPI / scan: constify first argument of struct acpi_scan_handler::match
One wouldn't expect a "match" function modify the string it searches for, and indeed the only instance of the struct acpi_scan_handler::match callback, acpi_pnp_match, can easily be changed. While there, update its helper matching_id(). This is also preparation for constifying struct acpi_hardware_id::id. Signed-off-by: Rasmus Villemoes <linux@rasmusvillemoes.dk> Signed-off-by: Rafael J.
