[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [PATCH v3 4/9] xen/arm: gic: set_type: Pass the type in parameter rather than in desc->arch.type
A follow-up patch will not store the type in desc->arch.type. Also, the callback prototype is more logical. Signed-off-by: Julien Grall <julien.grall@xxxxxxx> Reviewed-by: Stefano Stabellini <sstabellini@xxxxxxxxxx> --- Changes in v3: - Add Stefano's reviewed-by Changes in v2: - gic_set_irq_type has been dropped by mistake in gic_route_irq_to_xen.
