Subject: [PATCH v2] PM: fix runtime accounting calculation error
Date: Fri, 28 Oct 2011 14:15:02 +0530 [thread overview]
Message-ID: <1319791502-17937-1-git-send-email-vbyravarasu@nvidia.com> (raw)
From: venu byravarasu <vbyravarasu@nvidia.com>
With delta type being int, its value is made zero
for all values of now > 0x80000000.
Hence fixing it.
Signed-off-by: venu byravarasu <vbyravarasu@nvidia.com>
