DEFINE_RES_IRQ returns struct resource type, so it is unnecessary to cast it to struct resource. Remove the unnecessary cast to fix the following sparse warnings: drivers/acpi/arm64/gtdt.c:355:19: sparse: warning: cast to non-scalar drivers/acpi/arm64/gtdt.c:355:19: sparse: warning: cast from non-scalar No functional changes intended.
