[PATCH v2 4/8] powerpc/xive: Simplify xive_core_debug_show()
From: Cédric Le Goater <clg@kaod.org>

linux for powerpc (32-bit and 64-bit), the rest · Maintainers:

Now that the IPI interrupt has its own domain, the checks on the HW interrupt number XIVE_IPI_HW_IRQ and on the chip can be replaced by a check on the domain.
