Rafael J. Wysocki 0f1b414d19 ACPI / PNP: Avoid conflicting resource reservations ... Commit b9a5e5e18f "ACPI / init: Fix the ordering of acpi_reserve_resources()" overlooked the fact that the memory and/or I/O regions reserved by acpi_reserve_resources() may conflict with those reserved by the PNP "system" driver. If that conflict actually takes place, it causes the reservations made by the "system" driver to fail while before commit b9a5e5e18f all reservations made by it and by acpi_reserve_resources() would be successful. In turn, that allows the resources that haven't been reserved by the "system" driver to be used by others (e.g. PCI) which sometimes leads to functional problems (up to and including boot failures). To fix that issue, introduce a common resource reservation routine, acpi_reserve_region(), to be used by both acpi_reserve_resources() and the "system" driver, that will track all resources reserved by it and avoid making conflicting requests.
