[ Upstream commit 8ca944fea4d6d9019e01f2d6f6e766f315a9d73f ]
ACPI_RESOURCE_NAME_LARGE_MAX should be equal to the last actually used resource descriptor index (ACPI_RESOURCE_NAME_CLOCK_INPUT).
Otherwise 'resource_index' in 'acpi_ut_validate_resource()' may be clamped incorrectly and resulting value may issue an out-of-bounds access for 'acpi_gbl_resource_types' array. Compile tested only.
