Subject: [PATCH 1/2] ArmPlatformPkg/PL061: remove duplicated PL061_GPIO_DATA_REG
Date: Mon, 13 Feb 2017 15:52:59 +0800	[thread overview]
Message-ID: <1486972380-24255-1-git-send-email-haojian.zhuang@linaro.org> (raw)

PL061_GPIO_DATA_REG offset is referenced in PL061EffectiveAddress ()
already. So remove the duplicated reference when invoke PL061GetPins ()
or PL061SetPins ().
