irqchip/gicv2m: Miscellaneous fixes for v2m resources and SPI ranges
This patch contain fixes for v2m resources and SPI ranges: * Fix off-by-one error when set up v2m resource end range in gicv2m_acpi_init(). * Fix the off-by-one print error for SPI range. * Use %pR to properly print resource range information. Both ACPI and DT should now print: GICv2m: range[mem 0xe1180000-0xe1180fff], SPI[64:319] Suggested-by: Bjorn Helgaas <bhelgaas@google.com> Signed-off-by: Suravee Suthikulpanit <Suravee.Suthikulpanit@amd.com> Cc: Lorenzo Pieralisi <lorenzo.pieralisi@arm.com> Cc: Will Deacon <will.deacon@arm.com> Cc: Catalin Marinas <Catalin.Marinas@arm.com> Cc: <hanjun.guo@linaro.org> Cc: <tomasz.nowicki@linaro.org> Cc: <graeme.gregory@linaro.org> Cc: <dhdang@apm.com> Cc: <linux-arm-kernel@lists.infradead.org> Cc: <marc.zyngier@arm.com> Cc: <jason@lakedaemon.net> Cc: <rjw@rjwysocki.net> Link: http://lkml.kernel.org/r/1450830263-28914-1-git-send-email-Suravee.Suthikulpanit@amd.com Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
