Subject: [PATCH] gicv2m: Miscellaneous fixes for V2m resources and SPI ranges
Date: Tue, 22 Dec 2015 16:24:23 -0800 [thread overview]
Message-ID: <1450830263-28914-1-git-send-email-Suravee.Suthikulpanit@amd.com> (raw)
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
