#1297170 — [PATCH] 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]

 Hi Marc,

 Sorry for this minor last minute fixup. This should go on top
 of the V7 of the GICv2m ACPI patch series. Although, this is
 not urgent.

 Thanks,
 Suravee

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]
